hi guys

as you all know i am still a rx7 virgin only had my 1st rx7 for around 12 weeks
now well when i got the car did a oil change and put 10 40w synthetic oil in the car and not knowing i had to use mineral oil so my question is this after 12weeks what kind of damage would i have done now to the engine and can someone please advise me on what the best oil to use now as i am going to do a oil change at the weekend :rolleyes:  :rolleyes:

I would doubt very much if 12 weeks would be enough to damage your engine, and it would depend on what the oil was, I only use Royal Purple fully syn in all my RX\'s whether turbo or n/a, but than I sell it so would be bias. Seriously Royal Purple is one of a very few that wont harm your rotary but would actually benefit it. Mineral is a crap oil and its only advantage I can see is its price.

Don\'t worry Chris there\'s lots of scare stories about using synthetics but hands up anyone thats had any problems due to using them. I for one use synthetic oil in mine and know of a number of others that do also without problems.

M@r]{, I\'m using 10w40 Royal Purple that I got from Gary.  I believe that this should be fine for road use with the occational trackday.

Castrol GTX3 15W-40 all the way.
Take care about the oil temps, as mineral oil will loose lubracation above 120 to 130 degrees.

Different oils will recommend different grades.

I would not see any issues at all with putting a 10w-40 synthetic in your car especially if the engine has been rebuilt as there are no compatability issues with seals over the last 10 years.

I personally run synthetic in my rotary and recommend it as a better option if the car is driven hard or modded as they are more thermally stable and therefore stay in grade better protection for longer without loss of performance.

Look up my thread on synthetics and the rotary, it\'s well researched as I run one myself.

Too many old wives tales here about synthetics, they are superior in every way and contrary to rumour they burn cleaner as well.

I seriously wonder whether the cause of premature failure in Rotaries is down to poor oil quality causing premature wear, certainly there is a lot of expert evidence that backs up this.

A decent ester based one is the best for the tips as it is polar and the best form of lubrication as used in all jet engines for the last 40 years!

If anyone has any oil questions feel free to visit the Opie Oils stand at Rotorstock, I would be happy to chat.
