Engine oil Shell or OEM Honda

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.

I drove a 2008 Honda Civic for 5 years with only oil changes and no issues, then I moved to a 2013 Honda Civic for 7 years with only oil changes and no issues. Since then I've been in my model 3 with no oil changes and no issues. So not a really big difference for me.

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.

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

Before I boosted mine, I would do 5K all the time. Now it's close to 4k, anything over that and feels like shit driving it.

You can use it for motorcycles I have in the pass only thing I don't like is my bikes don't shift gears super smooth with rotella also in my Yamaha owners manual it says in capital letters do not use diesel oil and I did and I fried my clutch plates and had to put new clutch plates
