I've searched, and yet again found differing opion on this issue.

I'm at 1,300 miles now.

I've changed the oil and oil filter @ 1,000 miles on past vehicles for the 1st oil/filter change, but I'm not sure if this necessary today, or even prudent.

It is my understanding that the factory fill of oil (break-in oil, if you will) has a high concentration of moly, and that it might be advisable to do the 1st oil/filter change at 2k or 3k, instead.

So, what does everyone here think?

P.S. - I've already added 3/4 of a quart of Castrol GTX 5W-20 (non-synthetic).

 

I never add oil. There is 1.8qts of oil between the marks on dip stick. The car is oil injected according to how hard you drive it. You will normally get 2-4k in that 1.8qts. I just change the oil and filter between 2-4k. This is my 7th rotary and what I have always done. Rotary engines run hot and that breaks down the oil faster.

 

Mine gets changed every 2,500 miles, regardless.

For the very 1st one, I'd change it after you've clocked 500-1,000 miles.

 

I change my oil and filter every 3k miles. I usually have to add .5 to 1 quart of oil every 1.5k - 2k miles.
