Engine oil RED LINE or ROWE

Red Line.

I like red line oils, because they have a bit more zddp which is nice for the rockers.

On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.

Ran Redline 5w40 when it became purely a summer car in ~2013. ... Not seals are leaking, no issues of any form. Car has been Cobb stage 2 91oct tuned (OTS, not pro-tuned) almost 14 years, with a Crawford v2 AOS, Killer B oil pickup + windage tray being the only reliability mods, and it doesn't burn a single molecule of oil.

As soon as my warranty is up on my SQ5 in November, I'll be going to Rowe Hitech Synth RS 5w-40. One of the very few true synthetic PAOs out there and on par with LiquiMoly pricing (USP Sells it w/free shipping).

Redline is great, used it for years in a track car.

My STI also used it for a while (0w40), but then switched to Rotella.

Redline user have been since I picked up my 04 WRX wagon two years ago. Auto crossed and rally crossed. Works great have had zero issues, also at 170,000 miles on the original engine and still running strong.

Not really . My tuner (jackal motorsports) recommends Rowe RS synthetic oil . Currently using LM molygen , it's ok but apparentlyThe RS is the best stuff

Got these Rowe bottles. Fully Synthetic. German. Lets see how it performs.

Engine was noisier with the mix vs. the previously used redline 5w40. Iron levels are up at 6.3 ppm/1000 miles Oil usage increased by 1/2 quart over the redline 5w40 TBN/TAN levels are worse than 5w40 at comparable mileage
