Engine oil Eneos or IDEMITSU
Regarding brands, if you want to stick with factory oil without dealer price, Idemitsu is the brand to get. I emailed Mazda corporate and they said Idemitsu is the OEM for their oil.
Pros: OEM for Mazda oil
Vehicle:
Mazda 3
I have used Eneos 5w30 in it since I bought it. This is a group 5 oil and I believe that it saved my ass. Last summer going to work my car blew the top radiator hose off. I was about 3 miles from work and so I decided to just drive it. The temp gauge was pegged all the way. Come to find out my radiator inlet broke since it was plastic. I was able to get the hose back on after work and filled it up with coolant. Replaced the radiator with an aluminum CSF two row and knock on wood everything has been good since. Not losing water or oil and no smoke coming out the tailpipe or anything.
Pros: engine protection, no oil/water loss after overheating
Vehicle:
Subaru
Mileage: 95000 km
I’ve had a few oil samples analyzed of ENEOS and the OEM 0W-8 and the results are promising at 3k intervals.
Pros: promising results
Mileage: 4828 km
I have a Sohn kit and run Idemitsu engine oil in the engine and Idemitsu premix in the Sohn. Runs lovely and smooth and the original cat is still doing the job.
Pros: runs lovely and smooth
Vehicle:
Mazda
We use Idemitsu for engine oil and transmission and red line for front and rear diff. Red line makes a good fluid for the transmission also.
I use Idemitsu Wankel Racing Oil. 10w30, I think.
Pros: Wankel Racing Oil
Vehicle:
Mazda
My shop has a racing team and I've been using it ever since he got a sponsor.
Pros: used by racing team
Cons: expensive
Idemitsu all day. It’s synthetic but what needs to be emphasized is the ingredient blend is purpose designed for a rotary to make the right lube + burn.
Pros: purpose designed for rotary
I've been running that exact oil in my rx8 for about 1k km now and its still as smooth as ever
Pros: still as smooth as ever
Vehicle:
Mazda
Mileage: 1000 km
I’ve used Shaffer’s and now ENEOS and T6 when it was the in thing and I can’t really tell a huge difference.
Pros: no huge difference
