I run M1 0w40 in mine, it doesn't burn much(qt every 4k or so on 10w30). Feels a lot smoother too.

Clearances, not tolerances are what you are thinking about. And no, they aren't looser.

I run 5W-20 in my Sienna and 0W-20 in the ECHO. Both start much better with the thinner oil, and I do see more consumption than with 5W-30. It isn't a lot and considering the easier startups I'm more than willing to put up with having to add oil between OCIs.

I would not skimp on oil quality or grade or do extended OCIs, and if your engine qualifies for the TSB, you can get a new dipstick with higher marks to increase oil splash on the pistons to help control the ring temps. Or you can just fill 10mm over like me so you dont have to get the new dipstick.

Cheers.


Thanks for that info. If thats the real issue, I would think a good quality full synthetic with keep things cleaner in the engine while holding up to the heat cycles better. I will probably just overfill a tad anyway just to be safe.

Quick little background for my relationship with this car. Got it about a 5 weeks or so ago from a family member. Service records showed pretty regular oil changes at the local quick lube place. Oil fill cap showed light varnish on the top end. Oil in the car at the time had some life left so I have been driving it for the 5 weeks after adding about 6-8 ounces of MMO to start the clean up.

Well today I whipped up a franken brew today for sure... I added 1 qt of ST 5w20 left over from the Civic's oil change, 2 qt's of Mobil Super 5000 5w20, 3/4 qt of MMO and about 6 ounces of Rotella 15w40.

I am going to give the thinner oil a shot. This car cost me $1500 so I am ok with trying the not so recommended. I'll run this for at least 5K see if it helped clean up the varnish.

No problem, another trick us to use a small file and make a light mark above the full mark on the dipstick, for ease of filling and tracking consumption.

My 1zz was pretty varnished as well, you may want to inspect and clean out the PCV system if needed, i did this in conjunction with checking valve specs. Completely soaked and flushed the valve cover/baffel system that was very gummed up with carbon and varnished. I believe that, along with using a quality high milage synthetic at conservative intervals has greatly helped the consumption and de-coked the rings. The cieling of the valve cover baffel plate seems to get zero oil sling from the cams somehow and had a dry brownish tarnish that resisted removal. Basically i think this engine destroys oil that cant hold up to the temps, and clogs the pcv loop and intake with the burning oil. You just have to keep up on the maintenance.

I don't think the OP will get an appreciable fuel economy gain from running 0W-20 or 5W-20 over 5W-30.

Just stick with what the manufacturer recommends.
