What is the best CONVENTIONAL oil???
#26
that's easy.....the best oil is Mazda's own brand. Use it and everything will be fine. DO NOT fall for the premix bullshit and all the other stupid gadgets or magic oils on sale here...I swear there are vendors on this site, or being paid to promote the stuff!
Don't use synthetics....how many time u need telling, Mazda tells you over and over again. Not only a waste of money, also totally unsuited to this very low stressed engine.

here's a good explanation on the synth/mineral debate....seems to be the wear additive/detergent ratio that's creating some issues.

Wrong
SM rating does NOT mean its the highest quality. It just mean that it has met the "newest" requirement/spec. but does that mean these requirement/spec results in "higher quality" ? Nope.
For me, I prefer SL and sometimes, SJ Rated oil. and people that knows oil should know why.

Yet, my experience has been similar to Squidward's.
I have over 150,000 miles on my 2004 MT, everything stock (no mods), 91 octane from Shell, Mobil, Chevron, or Union 76, 5w20 conventional only, never used premix. I used to top off with Castrol GTX conventional oil when it was $1.81 at Walmart up until 2 years ago when prices sky-rocketed. Last 2 years I've been topping off with Walmart Supertech brand conventional oil.
I should qualify that I do mostly fwy cruising. In the mornings, I start the car and go (no warmup) but I go very easily until the car is warmed up. I don't care what the temp gauge shows, I'll cruise gently for around 20 min before I'll even push the engine hard or attempt to redline to burn carbon out. Done it this way for 6.5 years on my RX8.
