Hey guys. recently turbo'd my S2K, and I plan on doing my second oil change.

I may drive my car in the winter (MAYBE on a nice day).

Below are my mods, I'm looking for some feedback on what oil to use and why...

(I tried using the search box, but kept getting an error. Help and comments would be appreciated).

- 2.5" stainless steel intercooler piping
- HKS super sequential blow off valve
- 3" polished intake pipe with K&N air filter
- RC 550cc fuel injectors

- SPA technique dual EGT/boost gauge
- Autometer Air/Fuel ratio gauge.

i have the exact same setup as you

Depending on how cold it gets around your parts, either run 5w-30 or 10w-30... i personally run mobil 1 and just sent out my oil to be analyzed... i will give updates when it gets processed

 

Interesting...'analyzed'??? ....meaning?

Thanks.

 

oil analysis, it looks at the oil and tells me what is in the oil... copper anti freeze etc... and i paid for the extra option that gives me an analysis of how long the oil will last etc...

 

I believe there is a whole section called the "oil journals" in the UTH stickie section.... not sure if it touches on FI or not, but it does breakdown what oils are better for cold whether.
