just noticed honda is going to 0w-20 on the '11 ody, wonder if that would improve gas mileage.

Sure it would. Mugen sells 0w20 as their "racing" oil & with increased CAFE standards, gotta squeeze every drop.

Probably also want to extend the oil change intervals to reduce the cost of ownership figures. The Honda 0w-20 is a semi-synthetic so they'll be able to recommend a longer run and set the monitor accordingly.

Won't significantly change mileage since at operating temp they are the same viscosity.

mileage minder comes on about 7000mi, regardless of mostly city driving or distance (we goto kansas/back, avg. 2000mi)

doesn't matter oil visocity or time frame.

0W-20 will give better gas mileage in a cold engine. Whether or not the improvement will be measurable depends on how many cold starts you do per tankful.

Also, 0W-20 will lube a cold engine better and so reduce wear after startup. The Ody engine has no premature wear issues, so the real-world wear benefit may be only theoretical.

I'm not saying the minder will "sense" the difference. I think they'll change the programming to reflect that more durable oil is now specified.

The real answer is probably they get it in bulk for a cheaper price. It may save a thimble full over the life of the van.

I live in Houston and have been using 0W-20 in my 2004 Oddy for about 6 months now. That said, because of all the heat we've been having down here, I thought about going back up to a 5W-20. Would moving back up to a 5W give it a little more thickness to help out with the heat or would that only be accomplished by moving from 20 to 30, which I wouldn't think of doing with this engine. Thoughts????

Excellent. Seems I'm ahead of Honda on this one.... I've been using 0W-20 full synthetic Amsoil since 2007 when the van was new.

The 0W-20 is synthetic and will take the heat no problem. At operating temperature, they are both 20, so no difference there. A 5W-30 would be thicker as you said, but Honda doesn't recomment that grade. Stay with the 0W-20.
