Engine oil Shell or ZIC

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.

I’ve been using it as well for nearly 50,000 kms now in my personal car without any issues.

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

ZIC - Dito ako nag stay, ang tahimik sa makina, both matic and manual. Malamig din sa makina.

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

Personal experience ko from 15W40 Delo Gold to Zic 10W40 to 5W30 Full Synthetic sa 1.6L Diesel Accent mas naging responsive & rev happy yung makina sa 5W30 Full Synthetic kahit sa 10W40 kasi na Full Synthetic hindi siya happy parang pigil yung makina & less responsive siya.

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.

Nothing wrong with LiquiMoly, but I personally find Shell Rotella T6 to be better. It is quite a bit cheaper as well.

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.
