Oil Analysis 6070mi 1GRFE

The Following is a copy/paste from my post at BITOG. Thought it may be of interest...

This run was used in conjunction with a Baldwin B253.

FWIW- My 4Runner loves this oil. By conventional wisdom xw-40 is too thick but it runs quieter and better than ever! There's no appreciable/measurable decrease in MPG compared with MC 5w-20 semi-synthetic. There is a noticeable improvement in general mechanical noise (these are crude, noisy engines). Most significantly it drives better than ever. The responsiveness is the best it's ever been. I think the VVti likes this oil a lot, that's all I can figure. For the first time ever it's pleasant to drive.

To any Taco/FJCruiser/4Runner drivers I'd highly recommend experimenting with some xw-40.

As far as my slightly elevated fuel... That's amazing! I spent two days at the house starting, pulling trees and then shutting it off. When I couldn't do anymore on the second day (my 46 yr old body isn't what it used to be) I went for a 5-6mile ride and then took the sample and voila! Raw fuel, go figure Science is cool...
:cheers:

Very cool! Interesting to hear about the different oil. I may give it a try as I am going to get some service done this week.

Thanks for posting this Chris, I found your post over on BITOG last week (didn't realize it was you though at the time). I've been doing a lot of reading to try and decide between 5W-20 and 5W-30. Since yours did so well on 5W-40 I think I'm set on 5W-30 now because I prefer better protection during the summer and at operating temperature over a barely noticeable fuel economy improvement with the lighter 5W-20. Correct me if I'm wrong with. Both are 5W so cold starts should be the same. I've been reading too much about this lately and found there's no easy answer to this, but it would be great to get some reassurance that the TSB about using 5W-20 (for all weather conditions?) is only for CAFE reasons and not longevity of the engine. I saw another post of your that you did change to 5w-20 for a time, but looks like you switched. That makes me want to keep things at 5W-30, right in the middle.

5w-30 would be a fine choice for all of the reasons you stated. You're correct about the 5w aspect of it too in theory at least. In some cases 5w-20's seem to flow a bit easier than 5w-30's especially as the additives breakdown (nothing to worry about if you do 5k or less). Another thing you have going for is NC vs Fargo ND. The number of morning that you start in -20F or less ranges from 2 to zero.

Just my 2cents
