Fuel Saving Tips


Using Neutral when Coasting in Modern-Day Vehicles

For years I have understood that using neutral burns fuel to keep the car idling while rolling, and coasting in gear uses no fuel because there is complete fuel cut. I however began using the neutral method again and due to less engine friction I am able to coast much further and many times pick up speed when I would normally be slowing down, which equates to better fuel economy. My actual results when filling up are proof that using neutral does actually work better in most situations. My in-dash fuel econ reading will stay at 99.9(max) while coasting in gear OR neutral, and when in neutral it only decreases once under 10mph.

Gas Station Pumps / Get consistent MPG scores

Have you noticed some gas pumps are overly sensitive to shutting off before your tank is full? Make a mental note of the bad pumps at your favorite gas station so your MPG scores remain consistent. Doug - Oakland, CA

straighten the road

When conditions allow on mountainous roads, steer a straight line, even if it temporarily crosses the center line. This will reduce friction, reduce the route distance and smooth the ride for your passengers.

Highest gear not necessarily "economy" gear

Hi! I was always lead to believe getting in the highest gear as soon as possible was best for economy. My Scangauge shows that often staying in 4th or 5th in my 6 speed car gives better Mpg - despite the eco indicator telling me to upshift!

Drive safely, not stupidly

Do not ever turn off your car when you are driving. You go from being an active, able to avoid driver, to a rock with momentum. Saving an extra ounce of fuel is not worth causing an accident because you couldn't accelerate or brake fast enough.

Timing Belt Change, 2005 Lexus LS430, 90Kmi and 10 years

Suggested is 90K miles, 10 years. I was right at that, 10 years 86K miles. When it was replaced, which included a lot of other things, like water pump etc. The original pump had a small leak. To quote the excellent mechanic "if you went one more year, coulda been big trouble". $1200 spent. Felt good. There is an after market brand that makes the original equipment named "Aisin", don't use anything but this company replacement equipment, belt, water pump, sensors, etc.

Avoid the Drive-Thru

Unless you drive a hybrid the Drive-Thru can be a huge waste of fuel. With a long lineup of vehicles it will take the same amount of time and save money to park and walk in, it's also an opportunity to stretch out your legs and back.

Being Considerate When Driving Long Distances

If a car has appears behind you that wasn't there before it means they're driving faster than you and want to pass. When you go through a small township you'll have to slow down so pull over for about 10 seconds and let that car pass. They'll be very grateful. Ever been stuck behind an RV? If you don't let people pass then you are that RV! If you catch a car not going your speed - flash your lights a couple of times. Isn't flashing your lights too aggressive? No, dangerously tail gating someone and honking is aggressive. Unless there is another way to communicate with the car in front of you I suggest a quick couple of flashes.

Accelerate at high RPMs and Cruise at low RPMs

Try to accelerate at or near your peak torque (this is the most efficient zone for the engine) and once you get to your desired speed shift up into a higher gear to bring the RPM to around 1500. Try experimenting to see if it makes a difference. your fuel consumption will be slighter higher while accelerating but the time you spend accellerating will be reduced which brings the average fuel consumption down. I used to accelerate at 1500-2000rpm, I decided to try accelerating at 2-3000rpm and my fuel consumption has improved by about 10%-20% over my last two fuel ups!

Consider the effect of speed/lack of.

It's no secret that higher wind resistance upon your vehicle hurts your fuel economy. However, what many people may not realize, and test have proven this, is that aerodynamic drag increases exponentially as headwind/vehicle speed or both increase. For most vehicles, the optimal speed for maximizing fuel economy is between 40-50mph. As you go faster than that, the aerodynamic drag increases at an increasing rate to your speed. Popular Mechanics ran a test of a Toyota Camry once. At 45, it achieved 35mpg. At 55, it was about 30, and at 65, closer to 25mpg.

Z-Max

I've been using this in my car oil, car/truck fuel, transmission both auto and manual, power steering, and 2 stroke equipment for about 17 years, pretty close to when it came out. It has saved 2 frozen 2X engines, kept me form losing an aluminum block engine, and just adding it to the oil will pay for itself in 1,000 miles.

Make it a game!

I have a terrible lead foot. The only way to fix it, and of course save gas and money, is to make it a game to get the best MPG. Not only will you save money on gas, you'll also drive safer, be less likely to get a speeding ticket, save excess wear and tear on your car and brakes, and learn some patience along the way. That's what helped me from the hight 40's MPG into the mid 50's in my '94 Geo Metro.

Watch the station's gallons

Some stations deliver more MPG than others. Watch for patterns. Sometimes it's the fuel, but other times the station owner has set the station's pumps to read high. (The station where I worked did this.) I notice one Chevron regularly says I've used 10-15% more fuel than another Chevron 12 miles away. Ironically, they also charged 16 cents more per gallon. I noted this discrepancy on several earlier tanks, but it was when I started using Fuelly that it came to mind. (SG said I got > 35, "actual" mileage was 30.5.)

Modern A/C System DO use more fuel!

On my 2015 VW Golf, I've been carefully watching my MPG. Now that the temps are consistent and my driving is too, I can monitor my fuel economy with A/C on and off. My route consists of 70% highway. 4 total fillups have been monitored 2 with it on and 2 with it off. I saw 2 MPG LESS with A/C on then off. The new systems are more efficient, but they still will consume a noticeable amount more fuel, especially in city driving.

Torque

Find the cross point of the Torque & Power curve of your engine and try and ride/drive close to this area, it will generally give you the best MPG.

Proper Vehicle Maintenance

A car/truck that is running properly will be more efficient. Take good care of your vehicle. Just because modern technology has almost completely eliminated traditional "tune ups" doesn't mean you should neglect your car, though - a clean air filter, fresh oil of the correct weight for your engine, properly inflated tires, clean throttle body, spark plugs changed at the maintenance interval recommended in the owners manual, etc can do wonders for your fuel economy. Also, taking care of your car won't just save you money at the pump, but also keep up the resale value and increase the longevity of your car's engine, transmission, etc.

Test your routes

Try different routes (provided they don't add a lot of extra miles on), and note traffic lights, their patterns, and if there are stop signs. As obvious as it sounds, a stop sign means you'll always have to stop/go, whereas a stoplight you have a chance of a green light.

Go shopping in early morning or late evening

If your schedule allows shop early morning on weekends and late evening hours on weekdays especially in summer time. You can avoid traffic (=better MPG) and use less A/C. Less crowd at the store also means you get your shopping done quicker.

Be light footed!

Throttle position (gas pedal) is the most directly controllable determinant of your fuel efficiency. While some may argue that your RPMs are the most obvious link to efficiency, you certainly won't be doing your mileage any favours if you are flooring it at 2000 RPM in 5th gear trying to go up a steep grade without losing speed! Counter-intuitive as it may seem, it is sometimes beneficial to downshift into a lower gear (raise RPM/torque) to reduce the amount of throttle necessary to maintain speed and increase efficiency.

Buy a motorcycle or scooter

My 4 cyl Nissan truck = less than 25 mpg...My Honda Shadow 750 55 + MPG. 2 years ago (at 51 years old) I wanted to buy a full size truck, but didn't want to increase my fuel cost. I ended up buying a new Honda Shadow 750. My fuel efficiency is well over 55 MPG and I enjoy riding so much that I am riding over 20,000 miles per year! Parking is easier, insurance is low, maintenance is low, and fun factor is high. The new truck? Never got it. Why should I buy one when I am always on my bike?

Coast In Gear

Lift off & let the engine do the braking instead of only using the brakes & a modern fuel-injection engine will use no fuel at all & older engines will use very little. Why? The engine is essentially stalled & is being kept moving by your momentum.

APPROACHING BUSY MAJOR INTERSECTIONS

PROBLEM: The light turns green, you're in the left lane but can't go because cars ahead are unable to turn left due to on coming traffic. Other times, you're in the right lane but can't go because cars ahead are unable to turn right, because pedestrians are blocking them. SOLUTION: As you approach the red light, see if anyone in either lane has their turn signals on. If you see a signal in the left lane, pull behind into the right lane and vice versa. If all things are equal, choose the lane with the fewest cars. More cars in a lane increases the odds that one of those cars will be attempting to turn. Doug in Oakland, California

Save $$$ with Better MPG and with Paying Less for Fuel

Saving $$$ is nice reward for challenging ourselves with hacking the MPG game. Another way to save $$$ is by paying less for gas. You might want to try a phone app called "Gas Buddy", which shows you prevailing gas prices in your area. Doug in Oakland, California

Medium Thick Commute Traffic / Your Best MPG?

Recently, I got some surprising MPG results. "That's odd," I thought, "because my hypermiling techniques haven't changed." So WTF? I recalled I had been making more freeway trips in slower moving commute traffic. Slower commute traffic is your "excuse" to drive 40 or 45mph-ish, where your air resistance is much less. During non-commute hours, when others are driving 70mph, if I were to be traveling at 40mph, other drivers would use my car for target practice. So, the lesson is that light commute traffic can be your best MPG friend, because it gives you the cover to drive at slower freeway speeds. Doug in Oakland, California

Coasting does help

When coasting, kick your manual (not auto) into neutral, well in advance of slow traffic. You'll maintain speed and use little fuel. If you may be stopping, downshift, and you'll save slightly more fuel (as your injectors turn off), but slow down quicker. Occasionally I have to commute 70 miles. I climb 2 hills and see as much as 1 MPG trip improvement, per the scangauge, by coasting. It also gains momentum for the next hill. (They are steep hills, for a freeway.) It is counter-intuitive, but the gauge doesn't lie. Oh, and after driving it 130K, the Neon still has its original brakes.

Don't top off at the pump

When you fill up, wait for the pump to click and then stop. I used to top off without realizing that almost 100% of that fuel is wasted either directly back through the pump to avoid spillage, or in your car itself because it is "over full" I saw a 3mpg improvement when I stopped topping off, all because I was paying for gas that never made it into my engine!

driving style

For cars with manual transmissions, shift sooner and drive slower. which often means just driving the speed limit. It's obvious, not much fun, but saves fuel. When I use the highest possible gear that doesn't lug the engine, I can get 12% better fuel economy.

Traffic Signals / Be Familiar with Patterns and Timing

Most of us repeat patterns of driving, such as going to work. For example, from my experience I know when I turn the corner at one signal the next light will surely be red. In that case, if traffic behind me allows, I simply crawl around the corner slowly enough to roll through the next signal as it turns green. Improve your MPG by becoming aware of your signal timings.
