^^^^^ and what would be the next best thing to use?

 

I like using 20w-50

 

That's what I use!

 

I use 20w-50 mixed with 1/2 quart MMO

 

I prefer the 10w-30, but the 20w-50 is a little more resilient against the heat, dosent burn quite as well as the 10w-30 though.

 

I use 10w-30 Moble 1 non-synth (costs a little more, but more then pleased with it).

10-30, any generic brand **** i can swipe from work works fine.

 

Castrol GTX 20W-50

 

I run Castrol GTX 10W40... going by the owners manual, that's the weight it tells me for my climate.. hey, it's what Mazda says, and they're NEVER wrong! LOL

Havoline 10w30. Used to use Castrol 20w50 - Havoline has a higher flash point (makes sense to use it on a rotory) and I found the 20w50 too heavy for the climate up here (Canuck). Then again, I don't think it matters nearly as much as we like to think it does. Use a Premium grade and keep it topped up!!

 

I run
20w50 racing oil in summer
10w40 el cheapo in the winter

 

And heres the debate about synthetic oils if youre interested: https://www.rx7club.com/forum/showth...ight=synthetic

what would you reccomend for meeh since i live in So CA , im thinking about 10w 30 or 10w 40 thanks a lot you guys are really helpful sorry im still a newbie

 

I run 20/50 yr round...
I live in FL,So the thicker is helpful and I dont drive it much in our 1 month of cold weather.

 

I use 20-50 and find it works well even when the external temperature varies from minus 3 to 34 degrees C on the same day. The critical factor is getting the engine temperature up when you start, even on a hot day it takes a minute or so to get the temperature gauge moving- then I get the car moving!

 

10W30 or 20W50 for me.

 

10W30, which is what more than 90% of car manufacturers use.

 

ditto

 

castrol 20w50 with 1/2 qt of MMM...MMM makes the oil thinner so I use the higher weight oil...cjf
