hey guys i have 00 si...running low boost (that's a garrett t3/t4 ball bearing turbo) on a pretty much stock b16...my constant oil pressure is between 80 - 85 psi on WOT am currently using Castrol 20W50 not synthetic just regular oil...i see my ideal oil pressure within couple minutes of switching on the engine (oil changes have been done every 2500, 2800 the most)....now i wana go full-synthetic what are the suggestions?? Should I even go full synthetic.....do i need to?? Let me know whats up?? thanks!!

 

if it is a stock engine you should be running 5w30 or 10w30 motor oil.

if you want to go full syn. i use Penzoil Platinum, great stuff

 

why are you running such thick oil? With stock bearing clearances, run the factory recommended oil weight. I personally use Shell Rotella T6 synthetic 5W-40 in my turbo prelude

PS. oil pressure is RPM dependent, it has nothing to do with throttle position

 

Brad Penn 20-50

 

They run these weights because of the fact that they are so good to the thrust bearings of the turbo. Quite a few use a Brad Penn, Valvoline VR-1 non-street oil, or Castrol are the best to use at those weights.

For this OP, however, doesn't need ANY of that. Stick with the 10w-30 Synthetic Pennzoil, Castrol (Full syn),or Amsoil, you'll be fine.

 

ok, however i did read some article about full synthetic oil not being good for ball-bearing turbos...don't know if this so or not??

No. Its fine. You can use the Synthetic on it, no problem.

 

Mobile 1 synthetic or Quakerstate Advanced 5w30 for me.

 

syntec wont give disappointments

 

Brad Penn 20-50 is pretty inexpensive probably less the most synthetics

 

ok synthetic oil is good period...but no one has mentioned it's use in relation to Garrett Ball Bearing Turbo....is anyone using Full Synthetic with a ball-bearing turbo....let me know....thanks!

 

FOR THE LOVE OF GOD, MAN , YES!!!!! Us ball-bearing charger users USE SYNTHETIC OIL!! Stop trying to split unnecessary hairs here from what you've read. IT'S FINE!!!

I know you're trying to be thorough but this is borderline Obsessive behaviour.

 

I've been using Rotella 15-40 on my stock b16a2 with journal bearing PTE5431 for about 10k miles now. Doesnt burn as much as it did when I ran Mobil1 Synthetic 5-30

 

Thanks mi boss but it better fi be safe than sorry...wha u tink??.....alright don't crucify me yet but what you think about the thinner oil and ball bearings...a mean which oil would be better (am currently using Castrol motor oil 20w50)....the thickier or thinner oil?? after this i'll be vamoose!! haha thanks

 

oopps

 

LOL this is a diesel oil and has special additives for diesel engines. I would not run that in my Honda. A bit on the thick side as well.

 

I would really take Shodans advice he not only knows what he is saying he knows turbos inside and out since thats what he does.Who better to listen to.

 

Which if anything would be a good thing as diesel oil is designed for real hard wear and tear. That is providing the correct grade is used.

 

15w40 is not a correct weight for a Honda. Synthetic oil is also designed for harsh conditions and is great for high rpm motors, JMO.

 

while that isn't exactly "wrong" about syn, one of the biggest benefits to syn is its excellent cold flow. the majority of wear happens on start up and syn will flow faster cold. it also doesn't sludge with typical changes and can operate at higher temps before breakdown. many race cars have pushed 300deg oil tepms with redline without the oil breaking down. plain petro oil would be done for at 300deg

 

Which is why it is good for Honda motors and DOHC motors. The oil will flow up to the head and cams better under a cold start and hold up better under high rpms and heat.

 

ok bro....but why you say 15w40 is not the correct for honda...i know honda recommends 5w30w or something like that but uuuhhmm taking into account my current setup mentioned initially above what would be the best oil (i know synthetic) for me to use in terms of weight and why?? Thanks!

 

Bearing clearances are the main factor and yours are oem so 5w30 would be my suggestion.

 

ok understood but what about the turbo it's a garrett ball bearing t3/t4...and the engine has over 75000 miles on it i don't know if has anything to do with it...am in florida temperatures here are not too bad..so taking into consideration all those factors...what u tink?
