what kind of oil does everyone use? brand? weight ect.? normal or synthetic or half and half?

i was told that if you use sythetic you cant go back to normal..is this true? some said it wasnt but then others said it would ruin my engine..hmm well if you used half and half would you be able to go back to normal?... thanks a million

 

no one? c'mon guys need a little help...

 

basicly, if you change your oil and filter often, it won't matter what brand or non synthetic or synthetic you use. i use full synthenic and i change my oil every 3 weeks and i hardly drive my baby. only on weekends and on day off.

 

i use full synthetic (mobile 1) and change every 2000-2500 miles. all i know is when i push my car to the max i want it protected with the best. synthetic can handle more abuse than dyno juice. its also better for the turbo than d-juice. im no frekkin expert but most of the big time boys use Mobile 1. i use 15-50

 

I have been using regular old Castrol GTX 20W50 every 2000-2500 miles with good results. I also dump about a 1/4 quart in every 350-400 miles.

 

I'm going to switch to Mobil1 Synthetic 15w-50 my next change. I also want to try the Bosch oil filter. I've got 101K on my original engine in my '93.


Grimlock, why do you have a 3rd gen in your sig when you own a TII?

 

Castrol GTX 10w30. I'll probably switch to 20w50 due to the miles on my motor (186,000).

 

I was told synthetic oils in rotary engines are very bad , somthing like when you turn the car off the engine keeps spinning. I may be very wrong,But my frends RX7 is going into mazda on friday for evry fluid to get changed what oil is the best for a TT rotary engine?

also sorta off topic I also herd it is bad to use any spark plugs but mazda is this true?

Thanks

 

Redline Synthetic 20w-50 in the summer.....

 

I use Castrol GTX 20W50.

 

Ive always used synthetic blend, 10W-30 or 20W-50. Ive heard arguments both ways.
