When i got my RX-7 i had my dad look it over. He looked it over, decided i needed a tuneup and an oil change. Well i changed all the plugs wires distrib cap and all taht, he did the oil. He used 4 cycle. I didnt find that out until oh about 1500 miles later. How bad is this, and how soon should i change back to 2 cycle

Your car takes 4 cycle engine oil, just a regular SAE 10W-30 or the likes....

BigJim

ive been reading in a ton of other threads that ur supposed to use 2 cycl

Noooooo!

You can pre-mix 2 cycle oil in your gasoline if you are not using the OMP, want added lubrication, etc,etc.

The engine must have regular engine oil, and you should follow the chart on the underside of your hood as to what grade to put in. Most guys use 20w50 in the summer, and go to a 10 or 5w30 when the temps start to drop. Under no circumstances should you put 2 cycle oil in the crankcase!

maaan ohhhh man... 4 stroke in the engine.... you can premix 2 stroke into the gas if you disable your OMP, bu if you didnt disable the OMP do nothing with 2 stroke oil.

BigJim

Holy ****, he put 4 cycle in the crankcase? If you haven't changed it yet, do it NOW. heh Like they say above, you wanna use regular engine oil as far as the crankcase goes.
