Engine oil Shell or OEM Mazda

Rotella 15W-40. I put that shit in everything. My Yukon, my Fit, and all 3 motorcycles. It’s legit.

We used to commonly use Rotella in our heavily modified Mazdaspeed 3/6's to combat the same issue. It worked great and the only problem we ever had was with what we called the "black death".

Rotella T6 5W40

I run Rotella T6 5w-40 full syn Heavy duty Diesel engine oil in all my small engines with good results. Scooter, ATV, lawn mower, Honda car, and my F350.

Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.

RotellaT and Wix. Since my first turbo in 2007.

I used Rotella T6 in my old Subaru. It solved the oil consumption issue that boxer engine had. Seems like most people on NASIOC run T6. So if your car burns oil, it's worth a shot.

I've used it in my Z06, Suburban, my wife's Ford Edge Ecoboost and my old Gixxer and R6.

It's a good oil and cost effective.

It's synthetic, has decent additives and won't hurt anything in any of your vehicles.

Rotella T6 is a great oil for these cars, and it's what I use.

Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....

Love these high molly low viscosity oils. Absolutely the best out there
