Engine oil VALVOLINE or Shell

Y'all might call me a heretic for running Valvoline restore and protect 5w30 in my 4.0T.

Any oil that meets API SP and is the right viscosity grade more than likely is at least as good as the oils specified by the OEMs.

I don't know what it's doing inside my engine but I just did my 2nd oil change with R&P and noticed my dipstick looks new now. No signs of any varnish, just shiny clean metal.

Mas smooth siya kesa sa shell long ride tapos fully synthetic at API SP na din.

Yung sa pcx160 ko, bago ako lumipat sa amsoil dati ginagamit ko yung shell advance fuel save 10w-30 fully synthetic. Goods sya smooth sya gamitin at maganda performance

Same tayo ng Unit OP (Aerox V2)

Natry ko na both yan and mas nagtagal ako sa shell longride. Sa opinion ko lang mas smooth sa Makina yung shell long ride yung ultra scooter smooth din naman pero nagstay ako sa longride kasi ayun ang recommended viscosity sa Manual ng Aerox V2 (10W-40).

Shell ultra 15w-50, been using that in my reborn for 3 yrs now, buttery smooth.

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

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 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.
