Engine oil RED LINE or MOTUL

Used to use Motul, now switched to Red Line for the higher zinc content and high heat stability. I rallycross my daily so high RPM and high heat.

Motul X-clean efe for my 2016 WRX! 5w30. Hands down the best oil for the turbo FA20 engine.

I've had good results from Blackstone with running Motul X-Clean EFE 5w30. It has a high HTHS value so it keeps it's viscosity over time, from what I understand.

Personally I use Motul 8100 Ecolite 0W-20.

Redline 5w 40 since break-in, 254k miles later engine still going strong. Plenty of other repairs done, but no internal engine repairs required.

Oil and filter change, switched to motul 4100 15w50 (thanks Bernardo on the recomendation)

Completed my first oil change at 5k miles with Redline 0w20 and a Mann filter.

Been using motul 8100 eco

I use Motul 300V. No complaints.

I had Blackstone do a Virgin Oil Analysis of Red Line 5w30 This sample of Red Line 5W/30 looks good in testing. The viscosity is just a little above our \"should-be\" range for unused 5W/30, but that's common to see with some brands, and it doesn't show any sort of problem or deficiency with this oil. The additive package is typical of Red Line. They use a lot of molybdenum anti-wear additive. There's also some silicon, which is good to know about since silicon can also show dirt in used oil samples. It's an anti-foaming additive. No moisture or solids were found. This oil is in serviceable condition.
