I replaced my break-in oil with 0W20 for better gas millage.

Changed my oil at 2,700 miles. Went with Castrols Synthetic blend.
Printed a $10 coupon from the dealershipís website; net cost of O/F change was $29.

Same here, but the mileage went down. Turns out the oil change place hooked it up to a machine that automatically sets the tires to the dealer recommended inflation level... so I went from about 42 PSI to about 34 PSI. Could feel it, too. Taking my foot off the gas on the expressway slows me down pretty fast now, where with the inflation up, I could coast along for quite a good distance from 80MPH down to 60.

re: the oil -- Advance Auto had an "Oil Change Special" -- 5 quarts of 0w20 synthetic (either mobil1 or castrol) and a good quality filter (I think it was a Bosch) for $35. The filter alone was about $20 and the quarts of oil were about $9 each, so it was a good deal. Paid about $25 for a quick change place to do the dirty work.

I was at about 2450 miles.

So you're recommending that the higher PSI is better for fuel mileage? What about tire wear at higher pressure?

QUOTE (Wayne Gerdes (Hypermiling Expert))

Tire pressures are a very important key to higher fuel economy. The higher the pressure, the lower the rolling resistance, the higher the fuel economy. The absolute minimum you should use is the driverís side door or owners manual recommended tire inflation criteria. This is what the EPA and your car manufacturer sets tire pressures to during the EPA city/highway testing. MAX sidewall is what I would recommend for most as it is well within the safety limits of your car and tire and allows better FE than the pressure listed in the driverís side door. I can discuss but cannot personally recommend upwards of 25% higher than MAX sidewall as there are legal constraints we all have to live with. That being said, 50 + #ís on a MAX Sidewall rated tire leads to even higher FE. Pros, higher FE, less tread wear, more even tread wear across the treads width, shorter braking distances in a variety of conditions, and in many cases, even better handling. Cons, higher NVH (Noise, Vibration, Harshness).

Control, 35psi (manufacturer recommendation)
tires at 10psi = 3.7% increase in consumption
tires at 30psi = 1.2% increase in consumption
tires at 40psi = 6.2% decrease in consumption
tires at 60psi = 7.6% decrease in consumption
Bunch of tips to improve mileage here.

One of them is using 0w20 oil, which is why I used it...
QUOTE (Wayne Gerdes)
Quote:
Oil types and amounts are another important key to higher FE . A proper amount of low kinematic viscosity oil can do wonders for not only longevity of your ICE but the FE your automobile may be capable of. You should use oil with a viscosity that is within the band of your automobiles lubrication requirements. That being said, not all oils are the same. Many automobiles that spec 5W-20 can also use Synthetic 0W-20. Mobil1 0W-20 has the lowest kinematic viscosity as well as superior wear and breakdown properties vs. ANY non-synthetic I know of. About that level Ö I recommend that instead of filling the case up to the high level mark that you instead use just enough oil to bring the level up to between the high and low marks as specified in your owners manual. You lose capacity in case of a leak and have a very slight increase in oil temps but gain a slight amount of FE with a slightly lowered strain on the ICEís frictional components.

Tried to edit this in but couldn't:

As long as you stay under the max sidewall pressure for the tire, you shouldn't have any problems with tread wear or traction or safety. It does get a bit louder though. I only went to 25% over the door value (which is a touch less than max sidewall) because I misread the post I just quoted the first time I read it. The max sidewall for the tires in my base model is 44 or 45, I forget (can find it on tirerack.com).

That's the problem with those places. They always mess with the tire pressure, so it's necessary to check your psi right after a quicklube change.
