Engine oil Shell or Total

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

If It's like the 107 1.0 it would be Total Quartz ineo 5w30. Total Quartz is the official oil provider for Peugeot engines and it's the one recommended by Peugeot although any similar oil should work.

I been using Motul 8100 XClean on my BMW for 4 oil changes or 40000 km. Have changen service garage and they changed to Total Quartz 5w30. Since then engine is running much quiter

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.

Motul H-Tech 100 or Shell Helix Ultra

ito gamit ko sa nmax V1 ko for 4 years, sobrang smooth ng makina, at sa sniper 150 ko naman ng 2 years, wala din ako naging problem sa makina, at sa nmax V2.1 ko ng 4 years wala din ako naging problem. Ito din gamit ko sa ADV 160 ko ngayon sobrang swabe sa makina, tahimik na tahimik. Mahal nga lang talaga 500+ pesos ang price nito pero sulit.

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.

I ran T6 twice and didn't like it myself. I don't remember what it was that I didn't like about it, but I switched to Yamalube and haven't looked back.
