its about time i did a oil change on my FC i was just kinda curious as to what kinda oil everyone on here uses. i live in hawaii and according to the FAQs i should use 20w-50 but i was just wondering what brands everyone uses. i was thinking amsoil since i've used it on all my other cars.

 

yeah thats what i heard but why is synthetic so hazardous to a rotary???

 

It is a very heavily debated topic if thats even true. The supposed reason is because rotaries burn oil, and most synthetics leave behind a lot of junk. If you get a high quality synth like AMSoil or royal purple, they are fine. In reality, rotaries don't need synthetics. Just use Castrol GTX. Its the best dino juice due its clean burning characteristics.

 

Synthetic oil, when it burns, leaves ash, which basicly will clog your motor up. lol.. its like cigarrettes, it stimulates the motor and gives you 5-10 hp, but after 50k or so, your engine will probably freeze up and die.

 

at least thats what I heard

 

for the record, there are people that run synthetics in rotaries with no problems, its just a waste of money. What you said is true about many of the cheaper synthetics, though.

 

thanx a lot guys i think that i am just gonna go with castrol then rather be safe than sorry

 

That is completely wrong and mis-information.

Most synthetics (even the crappy ones like Valvoline) have less ash than most conventional motor oils.

Do some research before posting such bogus crap!

This has been covered countless times here and on 50 other boards.

Do not post if you are going to post old wives tales!
