In a stock BEAMS? If so you are killing your bearings.

Mobil 1 Synthetic 5w30 during winter, and 10w30 during spring/summer

yea i though that was a little thick but since i know nothing about the beams i didnt want to say anything.

I disagree. It's the thin oil that kills the bearings.

oh lord. ive heard sooo much about this that my head hurts.

Hi guys Just wondering toyota make a vvti oil for the beams what the difference between this and other oils .... i have had a bit to do w oil companies was sponsored by fuchs here in Aus with my historic sports car . now just finishing off my Dallara Beams hilclimb car im using shell racing solutions at moment w 75-90 gear oil used for the Hewland box would be good to hear about the vvti beams oil so i can see shell and ask the hard Question.....

Well ive been using it from the word go on my new engine.
Ive bought 2 boxes just in case they stop supply. Its not repacked at all ( backyard Toyota dealer ). Specified VVTi engine oil 10w30 and im happy, mind you my engine has 5,700 kms and ive changed the oil already 5 times
BTW i got a box of filters free , mind you i bought a lot. So an oil change which i like doing is only $15 for me

How? Thinner oil less friction and makes faster warm-up times which is good for bearings. Which is why new cars run lighter and lighter oil. New Toyota's run 0w-20 here from factory!

Ok, as far as I know thin oil gets too "watery" on high temperature. Warming up is one thing, but the oil must provide the proper viscosity during the rest of the time. With thin oil, it's possible that metal to metal contact occurs at these sport engines.
This is what I've heard.

I've searched the net a bit, and now I see what fvillota was saying Everyone argues about this thin or thick oil issue, and I don't want to start an arguing here as well. Peace

Maybe it depends on which climate we are living in.

That is the #1 deciding factor, try running some thick as molasses oil in -32F....instant seize!


The fact of the matter is the oil, regardless of weight, should operate within a certain spec at *normal* engine temperatures, within a particular age & build of the engine...
worn out bearings means more of a gap to put oil in, so thicker would be nice-ish, very very tight tolerances on newer engines can make better use of the thinner oils.
Colder climates need oils that can get to their proper viscosity at normal engine temps quicker, proper viscosity here being up to spec to the particular engine (worn, new, tight spec tolerances, break-in and so forth) etc.
