Engine oil MOTUL or OEM Volkswagen

I use motul in my heavily modified car though because it’s just that good.

Motul lang gamit ko since 2019, pero now ittry ko ung Pertua. Update kita sa performance.

I run motul 7100 in all my bikes it’s good stuff

My engine builder recommended what was 300v Power 5w40 at the time and is now 300v Competition 5w40 due to it holding up the best to fuel dilution from ethanol.

Motul is the gold standard - the IMSA cars you see with Motul badges really do exclusively use Motul. The shop I work with uses it in classic racing cars that are worth tens of millions.

I used to use Motul 5w30 in my track prepped FRS just as an added layer of protection, even if it is placebo.

Bought my JDM STI bug eye and with fresh 5w30 Motul 6800. Car runs well.

I feel it makes the car run more smooth when compared to the oil changes I did before that were not motul.

4100 turbo light? It isn't JASO MA specified for motorcycles and wet clutches. No damage from oil. Probably just rough gear changing and maybe rough on the clutch plates but you should be fine.

This is not fine. VW oils like 502, 504, 508 and 511 are not typical oils. They have a different additive package and the viscosity is different, like the extended performance 5w30 is not the same viscosity as a 504 5w30. The 504 is thicker and is closer to a 40w.
