Engine oil Shell or ZIC

Tried Shell Advance Ultra once no complaints, felt a bit quieter overall But I went back to Motul because the bike just felt more responsive with it.

I like motul for my Merc. But I just swapped in shell rotella 5w-40. Had some tick on startup and now the car feels smoother and quieter overall. I have a 92 with 73k

Shell high mileage oil.

One of the best engine oils, exclusive Zic lang ginagamit ko, and it's a Korean company so alam mong goods yan. Pero ako Zic X9 ang ginagamit ko, mas mahal kaysa sa M9 pero API SP naman na and may resource conserving certifications kaya mas madulas and mas tipid sa gas.

Been using it for over a year now sa daily scooter ko. Change oil every 2.5k kms, and so far, less wear and tear naman. Engine feels smoother, and surprisingly, di ganun kadumi yung langis pag draining time. Solid for daily use.

Rotella T6 15W-40. I’ve used it in all my bikes, cars, lawnmower. It’s the best option if you own lots of motors. Just change it frequently.

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.

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

When I tried it on my MT-07, though, I found a lot of false-neutrals that my bike didn't have before. I drained it out and put Motul back in after about 300 miles.
