Hi guys,
I recently bought my 07 sti and a shop in Santa Rosa, CA called FLI has done all of the upkeep and maintenance on this car. I have the paperwork/records on hand. It says that they've used only Motul 8100 series oil ever since they started doing the maintenance.
The records, however, don't specify which 8100 series was used. I could call them and get an answer but thought to get some other input and do some research on my own. I tried searching nation, here, and google but couldn't find a definitive answer.
I plan on switching oil between the summer season (which I'll be doing a number of auto-x events) with the Motul 300V ester-based oil and the winter/off-season with an 8100 series oil.
Which 8100 series oil should I use on my site, w/76xxx, that's a DD, and endures winters that reach single digits?
The options I'm looking at: 5w30 X-Clean, 5w30 Eco-energy, or 5w40 X-cess
Are there any big differences between them? Which one do you use? Oil changes will also be done every 3000 miles regardless of which oil I'm going to use.
I'm not looking to go to any other brand (I'm fine with the price). So please no comments on other brands.
EDIT: Here are the tech sheets for these two oils
X-clean
X-cess
