tips on improving mpg on my 316i se?

Question

i have a bmw 316i see 2000 model with a 1.9 engine and tips on improving my mpg ?

cheers

Answer 1

Items to use:
- Install Bosch Platinum +4 spark plugs - increases spark/burn efficiency.
- Use 0W-40 synthetic oil - more runny oil reduces drag, and check level often, even between oil changes. I found changing oil once between BMW recommended 15,000 mile interval is also a good practice.
- Use K&N drop in filter - allows engine to breathe easier.
- Avoid using wider tyres than necessary. A stock 205/60/15 tyre will roll with less resistance than a 225/45/17 tyre.
- Consider using "low roll resistance" tyres - though it is at the expense of performance. But hey, you want to have higher mpgs right?
- Clean your engine periodically with a fuel injector cleaner such as "techron".

Driving styles:
- Avoid start-stop traffic as much as possible.
- When in start-stop traffic, go gentle with the accelerator.
- When the traffic lights go green, accelerate at a reasonable pace, it's not a race with the next car.
- On highways, try to cruise at 60-65mph and avoid going over 70.

Things to do:
- Do not use the air conditioner unnecesarily (saps power from engine).
- Do not open windows unnecesarily (air drag)
- Ensure tyre pressure is at the correct PSI. 2PSI higher than specs is okay to compensate for temperature changes. But extreme over inflation is dangerous. If nitrogen is available where you are, it is believed that it holds pressure much more accurately than regular air.
- Avoid carrying unnecessary heavy items in the car.
- Avoid "discount" petrol stations. Go with established brands.
- Ensure wheels are in good alignment and balance; check for uneven wear pattern
- With your car jacked up, rotate each wheel by hand, there should be a little drag from the disc brakes. But a single wheel with too much drag could mean maladjusted brake and extra drag for the engine to overcome.
- Once in a while, say a few weeks, allow your engine to rev to 5,000rpm. This will blow out any carbon deposits that might be sitting in the engine.

Answer 2

Light on the brakes and light on the gas pedal, I run a BMW 323 2.5 litre and found that that high octane fuel gives more mpg. I use shell.
You must remember BMW are a drivers car and handling and performance is more an issue than economy, they are a heavy car.
Mobil one oil 0-40 will also help and keep engine clean and will give extended life to the engine. Once a year oil change or 10.000 miles is fine. if you use mineral oil then 5.000 or 6 months

Answer 3

properly, there are some which could improve gas mileage. A severe bypass intake and exhaust can help. even nonetheless, it relies upon on the motive force. often whilst human beings get those issues make the motive force race around as a results of fact it makes the engine sound extra aggresive and provides a extra suitable throttle reaction. Doing this could injury your gas mileage. Turbos can improve gas mileage, yet you wont be waiting to discover a aftermarket swifter equipment designed for extra suitable gas mileage. they are going to be tuned for overall performance. Superchargers NO!! the only element you're able to do to gas injectors or gas pumps if improve thier output. extra gas=much less gas mileage

Answer 4

Can't say more than whats already been said apart from getting a performance superchip fitted along with the K&N filter, that should improve fuel efficiency and give a little boost in performance as well.

Answer 5

Don't carry any heavy items unless necessary, inflate tyres 5% above suggested rate. Increase speed gradually. Read road ahead to avoid sudden braking. Fill the tank first thing in the morning when it is colder then petrol is denser and you get a little bit more!

Answer 6

Chris, these 2 guys have covered it Very Well ! Don't worry about the early morning fillup due to temp. change,myth busters covered that.They gave alotta good info though & ya gotta agree about the tire psi. With a bit higher pressure you'll have less grip, but less rolling resistance.Keep up with ALL maintenance.Good Luck
