Engine oil Shell or PENNZOIL

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

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.

I'm using Shell Advancen AX7 10w-40 na 800ml sa ADV 160 ko. Swak na swak yun!

2020 Telluride with 80,000 mi still going strong with Pennzoil Platinum Ultra at regular change intervals.

I often find Pennzoil Platinum Euro LX at 37$ for 5L at Canadian tire. They are all great oils.

I use 5w30, I used to use Schaeffer but it's too expensive now so I switched to Rotella.

Penziol platinum on my 23. change it every 5k and it’s still golden

Decided in the 5w-30 because the engine seems to run a bit smoother with the 30 weight

I've used a number of different oils in my XS400 over the past couple years, can't say I've noticed much of a difference other than when I used a 15W40 the engine was a lot noisier, going back to 20W50 and the engine quieted down a lot.

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.
