Engine oil Shell or FUCHS

depende sa oil IMO, pag mahal na oil ranging 500+ yun pwde yun isagad 6k, pero kung mumurahin, expect mo sobrang itim at dumidikit sa gilid yung oil at nagbabawas

I’m personally a big fan of shell rotella. That’s what I’ve always ran and haven’t had any issues. My 05 STI is at 163k miles still running strong

I use Shell Rotella T6 5w-40. Available at Walmart lol.

4.5 L is the Ideal for Mazda 6 2.5 non turbo, I'm from the same country as you. I'm using fuchs titan 5w30 for two years and I recommend you do the same, I noticed quieter engine.

Super love yung long ride sa XSR700 ko, swabe ng feel sa clutch and shifter.

Shell helix ultra o é o segundo melhor na minha opinião.

Can’t go wrong with Rotella T6. It’s marketed as a diesel engine oil, but gas engines love the stuff too. It’s just not great for catalytic converters, because it contains a high amount of anti-wear and anti-friction additives.

I'm using Shell Advancen AX7 10w-40 na 800ml sa ADV 160 ko. Swak na swak yun!

I run Shell Rotella T6 5/40 I live in Florida. Slightly high copper on the STI. The Tribeca is fine and purrs like a kitten.

I did use the Shell T6 Rotella 5W40 for 4 OCI's and then got a misfire issue. When my mechanic was going thru the possible symptoms he asked what oil i used. When i told him it's a full synthetic deisel truck oil he shook his head and said that not a good idea. Too thick, and that could have an impact.
