Best Oil, Whats the best oil Options

[windowlicker]

ya its kind of a waste to use synthetic blend on 7afe and 5sfe. I mean only if you're going to race your 7afe or 5sfe(which isnt really a good idea). I use valvoline, castrol, or any high mileage over 75,000 miles synthetic blend.

hell even though i rallyx the hell out of my 7afe in the desert, i still use castrol gtx 5w30. the previous owner of the car used nothing but castrol gtx and when i dropped the oil pan, i was super surprised that there was NO sludge or anything in the pan with an engine that had 180,xxx miles on it at the time. the bottom end of the engine was amazingly clean, so i figure keep using the gtx. personally, i don't really see the benefit of using any high performance oil in the 7afe or even the 5sfe during normal driving. i can understand the need on the 3sgte for synthetic since there is a certain amount of oil running through the journal bearings on the turbo and higher engine temps when its pushed hard. i always used mobil 1 in the srt4 i had, and it worked very good, especially after running the canyons so hard you could see the hot side of the turbo glowing red.

oh, and yeah, once you go synthetic, there is no going back. something about seals leaking is what i've always heard.

although the weights matter for the type of climate, royal purple is said to be the best, thats what I use.

most important thing is the filter. go with the oem toyota one. as for oil i like mobil1 5-30 synthetic. good stuff but has it disadvantages too... so toyota filter no matter what kinda oil!

Really? I wonder what they look like on the inside. In my shop, the teacher recommends Fram, as he had several filters cut open and fram was looooooooooooooooong. You want the most filtration with the smallest amount of holes for better filtration, otherwise the larger the holes, the less good of a job it is doing.

the bypass valve is an important part, which i believe some aftermarkets lack... correct me if i'm wrong.

I use Valvoline VR-1 Racing 20W-50. Have used it since I turbocharged my Celica in 2003. It's really not racing oil. Just regular good oil but it works.
