I have one but only use it for dusting the dash, console and other interior areas. Works really well for that. I never use it on the paint.

Another vote for Collinite. It's really great. I haven't found anything that beads water longer, including some of the new ceramic stuff.

You must be really old. No one under 70 drives an Avalon.

Not brand so much as viscosity. Just seems logical that a thinner oil might allow more blow-by.

So then regardless of what oil you use, it will have no affect whatsoever regarding blow-by? I was under the impression it did but I stand corrected.

But you side stepped my question. If certain oils are better at reducing blow-by then wouldn't that also be reducing fuel dilution? Maybe I'm wrong but that's what I've gathered from all my time here and on other sites.

Seems like a reasonable approach.

But it could "reduce" fuel dilution could it not? Better ring seal?

So then how do you decide which oil to use in your vehicles?

I think you can only make your own conclusions based on additives, base stocks, UOA's, NOACK volatility, HTHS, etc. Even then you can't be totally sure but using that type of info seems logical to me.

Saying that if two different oils meet the same specs and certifications then they will perform exactly the same with the same results is like saying that if car A gets the same NHTSA or IIHS crash ratings as car B then both will perform the same in a crash. The differences might not be huge but...

This all makes sense and is what I was thinking but wanted some confirmation from others. I'm still not sure whether I'll stick with 0w-20 or not. I might switch to 5w-30, even if just during the summer months.

Care to go into what effect going thicker or thinner would have ? Assume you have no clue, but thanks for contributing.

I don't want to debate thick/thin. I'm just wondering if oil viscosity would have any effect on the functioning of i-VTEC in the current V6 engines.

I had a 2002 WRX which I think was the first year they were available in the USA. Car and driver got a 0-60 time of 5.4 with that car and I believe some other car magazines were getting 5.7 - 5.9. So it seems not much if any improvement from what it was 20 years ago which is surprising.
