2nd gen RX7

[2slow2serious]

I own an 87 RX 7 and i was wondering if 10-40 castrol GTX is good for my 7 and which is the antifrezee you recomend i put in my 87 RX7?

Thanks

the good oil viscosity will vary with the weather where you live, and any antifreeze will work just fine, im staying out of the premixed stuff, and in summertime, i just do a rad flush and i use water. i use antifreeze when its starting to freeze, obvioulsy

and always use mineral oil, unless you've removed the omp

mineral oil? what if i he already used 10-40 castrol GTX Motor oil what could happen?

shouldnt you use 20w-50?

20-50 is the generally accepted viscosity for the rotary. And use regular Prestone with distilled water for coolant.
