Engine oil Shell or Motorcraft

Full synthetic Motorcraft for my Shelby, Roush, SHO, and Focus 1.0 ecoboost.

Ford performance oil filter for the Shelby. Motorcraft for the others.

Why? I had a Ford tech tell me any and all problems they'd ever seen with a Shelby engine involved one that used non-Motorcraft brand in engine or filter.

I run 10w30 motorcraft because my 300 doesn't dry start as bad with it

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.

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 think factory recommendation is Rotella but honestly you can go with any high quality oil. I have used Rotella, Castrol, and Valvoline synthetics in my 500 and I honestly don’t think it matters.

I switched to Rotella T6 (5w-40 Full Synth) after running Penzoil, Chevron, Castrol, Mobil, regular non-high mileage 10w-30 dinos in that order over 4000 miles. Worst of this bunch was Mobil and Chevron, the HLA tick was unbearable, even right after the oil change.
