Engine oil OEM Mazda or ELF

I use Elf Oil and I change mine every 5-7k miles.

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.

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

They should be using 0W20 full synthetic oil (not synblend crap). Its not going to hurt running the 5W20 in it instead but next time mention it at write up. Mazda claims benefits such as better cold start protection and better efficiency among other things.

I currently use ELF Exellium NF, Motul is good too I was tempted to get it....you can also check out ECS Tuning, they sell Lubro Molly now, I think that's gonna be my next choice and I might stick with it. I've used Amsoil for about 20K miles and liked it too. Otherwise, you can't go wrong with Castrol Syntec 5w40 either, I've used it since new all the way till 60K miles.

I used ELF Excellium NF 5W40.

I personnally use Elf and love it, best oil I ever used so far.

ok i just did an oil change today. i put in Elf Excellium 10W50 Full Synthetic. anyways, the difference is awesome. much more free reving and "wanting to go faster" feeling. before oil change it felt tired and revs were lazy and engine had a 'fuzzy' sound when accelerating. anyways, all is good now

I use Elf, I switched over and won't go back.

For the record, this is NOT the exact replacement to Mazda 0W-20 GF-5 with Moly - Synthetic Engine Oil.

While this has high molybdenum, it's still a different formula from Mazda's own proprietary blend.
