Witch would you guys prefer on a 12a. And 10/30 or 20/50?

 

Use whichever makes you warm and fuzzy inside. 20/50 in your climate.

 

dont let anyone sway your opinion. do your research and you will get your answer.

 

Have best of both worlds and use semi synthetic. I have used semi syn oils since forever and never had a problem. Oh and the hotter the climate the higher the number rating on the oil should be, so in Cali 20/50 would be the go mate

 

You will likely never "have a problem" with any oil you use as they are all made to meet the minimum standards necessary to function.

Seriously though, whether you chose synthetic or not is irrelevant. Both will work fine in the rotary.

I run whatever oil is on sale when I need it.

 

Cool. cause i've been using 10/30 and some people say thats good but then some people say i'm gonna blow my motor cause its too light and might overheat my car

 

oil is oil i usually just go with what ever the owner manual chooses and get synthetic instead of conventional

 

You'll hear people talk about which oil, which viscosity, synthetic or mineral, which brand, but you won't hear people talking about blowing their motor because they used the wrong one. Dunno who said that or in what context, but that strikes me as a strange warning. (BTW, people use all of these variations of motor oil and blown motors almost never come from oil related failures)

As long as you're using the specified oil or something close to it, and you're keeping the level and changing on factory intervals or better, you have little to worry about.

The type oil in regards to synthetic or non-synthetic is question of personal preference and the application and driving style. I have used both and different brands but have never had any problems. It can also be that I premix also. i hope this helps. There are a lot of people who are biased to petroleum brands and what not, but at the end of the day do some simple research and if you still have questions call a reputable rotary shop.

 

Im using castrol gtx 20w50 every 5000km's.. works well.

 

when I bought my 87fc a few years back and changed my oil with synthetic (royal purple) I was set to believe the you can never use synthetic oil for the rotary after my fc had to get rebuilt after I did, and I evenheard it from from a mechanic who owns a 1st gen but after hearing multiple opinions saying that I can then I'm pretty sure that my engine was already in bad shape when I bought it. Now I have a 94 fd tt with some starting issues and I'm wondering what could be the reason cuz I'm thinking spark plugs but can hear the clicking, flooding possibly but sure it's not the case cuz I make sure I let car run a few minutes longer after I park to rule out flooding, maybe oil bulid-up? Idk but could somebody give me some insight on this matter...thank in advance

 

^ Not related to your oil.

 

Thanks for the info I think I'm gonna try out regular oil
