Hi guys please help me with my new 04 8 ,
guys I realy want to know what youll mean by the "CAT"

and previous owner gas used MOBILE 1 Synthetic engine oil earlier is it ok if I use the same or to use a non synthetic castrol or velvoline

you r kind help regarding this is much appreciated becuse in our country there are no rotary engine specialized mechanics and there are only few rotary powered cars

thanks

 

CAT = "Catalytic Converter"

All oils are fine, mixing them is fine. thicker is generally better, synthetics are generally better, but a thin dino oil oil changed every 2,500 miles is far better than a thick synthetic changed every 4,000.

Oil weight/type is not a significant factor in long term engine health. There are many other failure points that have nothing to do with oil. Basically if you don't run it out of oil, it won't be a factor. Frequent oil changes matters mostly because it helps keep the OMP injection lines more free of crud, and limits bearing wear (that will only matter over 100,000 miles of that oil usage)

 

thank you so much for the erly responce as I was stuck what to do , thank you so much

 

Welcome,

I use dino 10w30, changed a lot. likely every few thousand miles.

My CAT broke.

Check out the threads in my sig for new owner stuff.

And, again, welcome

 

Mazda actually recommends against using synthetic oil. So if you switch to conventional oil, not only will you save money but you'll have the satisfaction of following orders.

I see from your IP address that you live in a warm part of the world. While, as RIWWP points out, weight isnt a big factor, don't go any thinner than the 10w30 04Green uses.

Or install a SOHN adapter, inject 2-stroke, and use a medium to high weight synthetic for the high sheer environment of the e-shaft bearings without worrying about what dirty 4-stroke injection is doing inside your engine (which, hint: it's still cleaner for your engine than gasoline)
