Fuel Saving Tips


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!

Clear the Clutter

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.

Freeway Game / Whoever displays up their brake lights loses!

In stop and go freeway traffic, have you ever noticed the car ahead of you riding the bumper of the car ahead of them so closely that they are constantly displaying their brake lights? THEY'RE AN IDIOT!

GONE WITH THE WIND (cute, eh?)

On a Oakland to Los Angeles trip, my return north was 10mpg LESS! My driving style was the same in both directions. WTF - I recently repeated the "bad leg" of my LA trip and got the same 54-ish MPG in BOTH directions. So why? - If you sail, you know the wind normally comes up around noon and dies after sunset. - This time I traveled north at night INSTEAD of day. - During the day there must be a southerly wind blowing along California's Highway 5. - With "local knowledge", as sailors call it, drive accordingly. Drive with a tail wind and return when conditions are favorable. - As sailors say, "May you always have the wind at your back!"

Turn off the A/C when accelerating

Accelerating uses a lot of energy and fuel. If stopped at lights, or a junction, try turning off the air conditioning for a few moments until you have accelerated back up to cruising speed. The air con will only put the engine under extra load whilst accelerating back up to speed. You can also try switching the air con off when going up hills.

Good mileage

Drive as if the highway patrol was following you, or as if you were taking your driving test. It will improve your mileage.

Freeway / Help Truckers Pass Easier

On the freeway when trucks pull out to pass on my left, if there's no traffic behind them, I will key off my car. This does two good things. It gives me a chance to spike my MPG with a Pulse and Glide moment and, because I slow down, it helps the trucker pass easier, as they will normally pull back into my lane ahead of me.

Lower your Aero Drag by going a Tiny Bit Slower

I figure 53mph is close enough to 55mph that other drivers will simply believe I'm trying to go 55mph but that my odometer is slightly off. Doug Oakland, California USA

Think of high MPG as a Game

Saving $$$ at the pump is nice, but that's NOT my primary motivation. Are you a competitive person, like me? If so, treat each tankful of gas like the "start of another game" as another chance to beat your all-time MPG record. Doug Oakland, California USA

How I got 54.65mpg on the Freeway

I recently got 54.59mpg on my trip from Oakland to Los Angeles, a 373 mile trip, with my 1989 Civic hatchback. Here's how I did it. Have you noticed freeway cars travel like packs of animals? There's often a huge blank space between these groups. When my car is in that void, to lower my car's aero drag, I use that time to slow down from 53mph to as slow as 45mph. When I see traffic approaching behind me, I'll speed back up to 53mph. This keeps me from getting shot. :) After the pack of cars passes, I'll go back to 45-48mph. Doug Oakland, California USA

New air filters don't change MPG

Contrary to popular belief, especially what you'll hear from the companies and stores trying to sell filters (hint hint), changing your air filter will NOT improve your mpg, nor will it extend the life of your engine (BTW, dirty filters filter better). It will remove a slight restriction to peak horsepower but not save gas, so feel free to put that money elsewhere.

Switch your engine off at traffic lights

If you know the timing of the traffic lights and/or you know you're going to be stopped longer then 10 seconds switch your engine off. (this works best if you have a modern fuel injected car, carbs tend to be very wasteful when starting). If you have a manual transmission put it into first gear so you can just press the clutch start and go
