Engine oil LIQUI MOLY or Shell

I've been running Rotella t6 and a wix oil filter for years on my 04, 3k miles everytime, and it's currently still running with 245k miles.

First oil change after filling with T-6 on my 2002 Saab 9-3 (that didn't have a kit on it) I bought with 130k miles on it was really black, almost a bit sludgy. Next few oil changes quickly got better as the detergent broke down sludge in the top end and cleaned the motor up.

I used Rotella T6 for the past few years and no issues

I run liqui moly 4100. I run 5w40 because I want something a bit thicker than what the manual calls for.

Liqui Moly Toptec 4100 5W-40 works if you feel like you need something thicker, but these diesels don't run crazy hot like gas + turbo engines.

oks yang oil

pero maybe wag mo sagarin sa 6K

go for around 3k-4k dun mo na palitan

I am using shell advance ultra 10w-40 and hindi pa ako nagkaproblem dito sa oil na ito.

I'm not trying to put down LiquiMoly as a brand, but SAE is SAE. Now I wouldn't choose like a cheapo store brand, but big brands like Valvoline, Pennzoil, Mobile, those are all gonna be pretty much just as effective at completing the job they were designed to do.

Stay away from rotella conventional. I’ve heard and now as well personally have had a turbo grenade due to their oil quality, that’s the conventional anyways.
