I did some serches couldn't find anything. So im going for my first oil change in the FD. How much should they put in and what weight. Right now its summer in cali so it avg about anywhere in the 80's F. So what weight should i use

 

10w-30

 

any oil as long as its not synthetic?

 

Any oil is fine. Synthetic is best, really, but there is an ongoing debate about whether synthetic is safe for rotaries (though I have never seen or heard any credible evidence that it isn't) or if it is worth the extra cost (it is clearly better oil, but you still have to change it often and rotaries aren't failing from lack of lube, so it may not be worth it).

Many people use 20W-50 in warm climates. Mazda recommends 10W-30. Either one will work fine.

You couldn't find anything?

Just from the last year:

Not to mention the fact that oil weight is covered in the owner's manual! Although, since they do say not to use synthetic, I'll give you the benefit of doubt by not trusting it...

 

i juss barely bought the dang thing but i do need to pick a up a manual ur right about that ryn

 

Thick oil in the summer, thin oil in the winter. The wheel has already been invented.

 

it would probably have been better if wheels with spinning hub covers had not been.

i use castrol 20-50 but i live in texas. red line oil is good but expensive. i use those in the gear boxes.

 

AGREED!

You can also buy oil specifically designed for the rotary a.k.a. Mazdaspeed Rotary1 oil. Cost=$107.00 plus tax & shipping for a 4 liter can. (about enough for one oil change)

 

^WTF $107 for 4 liters --- the oil will have to be changed in 2-3k miles whether it says rotary oil or not.

That's like 22 liters of mobil 1 10-30 oil (what I use) and that stuff isn't cheap either.

 

Valvoline VR1 20W-50 here in FL, where its always hot ...

 

Funny i even found all the info i needed about this topic as I just did mine for the first time today. I've only driven the car 1,000 miles though..

 

uhh isnt valvoline one of the bad for rotaries synthetics that blew up the 737?

 

I just throw in some highly-refined vegetable oil and forget about it for 2500 miles or so....

 

caster oil

 

I think the Valvoline I use isnt synthetic
