I used to use 10w30 for my 2.4 22RE, but now I have the 2.7L 4cyl.

Would you still use 10w30? And if I have different brand names of regular motor oil for 10w30, can I mix them? Thanks guys.

I think 10w30 is what I run in my 2.7; depending on the weather in your area, you may need to run a thinner oil in the winter, but if your area doesn;t get too cold, 10w30 is fine.

As for mixing different oils, I've always been told that the biggest no-no is mixing detergent and non-detergent oils. If the oils you want to mix share the same properties -- and the same additives -- then mixing shouldn't be a big deal.

Oh, and no mixing mineral (dino) oils with synthetics -- that is a definite no-no.

Toyota Canada recommends 5w30 year round here in the Canadian Climate .... I'd say check your owners manual .

It never came with one when I bought it...bummer

when in doubt.. 10W-30. it's a one size fits all type oil. I live in a very hot climate (FL) and I just ru n 10W-30 Synthetic Mobil 1. I used to run 15W-50 Mobil 1, but went back to the thinner stuff. I can't tell the difference with either in my 3.0... so 10W-30 is plenty. Biggest thing you can do for your engine is :
A- DO NOT RUN FRAM OIL FILTERS!!!!
B- Run a synthetic motor oil (not castrol it's fake synthetic). A synthetic will allow the oil to flow in cold temps and when it's really hot it doesn't cook off. bang for the buck... Mobil 1 at Wal-mart. 5qts for $20.

i think the newer engines recommend 5w30 for all-around usage. the 2.7 doesn't have as sloppy tolerances as the old 22R, so the thicker stuff might not have any benefits.

mobil 1 is petroluem based oil so doesnt that make is a fake synthetic also. i put mobil 1 in after 10,000 miles on my motor and my truck now has a slight rod tap.

One thing I've been told by my neighbor whos a big hot rod guy, is NEVER mix different oils of different brands......different ingrediants that they all use makes it hard to find 2 that won't mix badly with eachother.....unless you're into experementing with things that might mess up your motor, then ya can post up later!! <img src="/forums/images/graemlins/smile.gif" alt="" /> <img src="/forums/images/graemlins/smile.gif" alt="" />

I've always run FRAM filters, and like we've talked about before, as long as you check the anti-drainback valve then you're good to go. In the 3 cars I've owned, always changed the oil every 3K and the filter was always full of oil when I removed it. Seem to work for me....no oil-related engine problems yet......

how many miles do you have on your engine now will?

ive been running that dino mobil for a while. it used to be called drive clean blend but then they switched it to clean 5,000 or something.

i know they say not to mix oils but how much of an adverse effect can you have from mixing them? i dont think it could be anything too catastrophic.

Mix oils to you hearts content. They are absolutely required to be compatable, and are.

Mixing an old SC oil with a newer SJ oil gives you the overall properties of the SD. Mixing a 10w-30 with a 20w-50 does indeed give you roughly a 15w-40. Mix synthetics with regular oils if you wish. Then you can brag about running a synthetic blend.

The only oil mix I wouldn't do is running a non-detergent oil. It does promote sludging and certainly isn't good in a modern engine. Modern being anything made after the early 60's in this case.
