I am hooked, the next oil change I will switch over to synthetic oil. Right now I am running the original motor with 185,000 miles and probably a bunch of dino crude. After I clean all the crude out with power foam, can I then change over to synthetic oil?
I thank you all for the research. I am tired of hearing strict opinion, it's nice to hear real facts once in a while.

PLugs always look a very nice cocoa brown.
It does get a little expensive though. I pay about $7.50 a quart. Seems worth it to me though.

That's not something you forget.
Conversation.
Timmya - "My car has been running strange"
Me - "When was the last tune-up?"
Timmya - "Not too long ago, the begining of last year, had the oil changed then too"
Me - "You're kidding?"
Timmya - "No, why, is that bad?"
Don't bullshit, you'll almost always be caught.

timmya2 thats just sad. Try changing your oil and cleaning your plugs and distrib. Might run a bit better.

I've already been over it with him heb09.
Full tune-up; new plugs, wires, cap, rotor, oil, oil filter, fuel filter.
Cap and rotor you could probably go without, just sand the points with fine grit sandpaper.
Back to topic -
I used the cheapest oil i could possibly find, since i had to add a quart every 700 or so miles, i was doing half an oil change inbetween my actual oil change. I figured why spend alot of money on expensive oil?
Upon taking my engine apart, the internals were in excellent shape by the way. Only reason the engine failed was due to a previous rebuild, 4 corner seals parallel to one another were not replaced resulting in two bent apex seal springs.

Im not here to argue or state a certain point. Just explain what synthetics did to me. I own a corvette which praises synthetics as does my wifes lincoln ls. I had an 85 se that when i bought it only had 40000 miles on it. The normal style oil was ran in it from day one and i didnt know there was a problem with running synthetic. I had mobil one 10-w30 put in and thats when my problems came. I went from having a leak free car to having one that leaked all over the place. Im talking a puddle after leaving it parked over night. Further investigation unvieled the problem. Se's have the oil cooler that is in front of the radiator. Well there are braided lines connecting to the block and are what the oil go through. Mazda says the cause was a chemical reaction of the mobil 1 synthetic eating through those hoses. Not from the oil out of the bottles, but after its burned through the motor and recycled through the oil system. Im not experienced with the internals of rotaries but it was something that after the combustion seperates the oil back to the pan. I quickly put old style valvoline in it and the leak didnt go away but got alot less apparent. My point is those lines are cheap but u have to replace to cooler as well, somewhere around 500 bucks total for everyhting. To make a long story short ill never run synthetics in an se again. It might be fine in other rotaries but not in a gslse. Thanks, Karson

I run Royal Purple 10w30. And RP premix. 1/2 quart per fill up. Read Royal Purple's webisite and do some FAQ reading. Also, read RB's web page about the praises of Royal Purple. And yes, my OMP still works, I just want some insurance because the street port motor only has 8000 miles on it, and it's been built 10 years ago. No smoke on startup, and runs 60 lbs of pressure at 100* at 3k rpm.

I've had no problems with AMSOIL 20/50 racing in my first gen ITA car or my FD. I also like Valvoline VR-1 racing oil. In the winter I use Valoline 10/30 semi-syn or whatever its called.
edit: I also premix with AMSOIL 2-cycle.

I had a friend that ran redline and at 200k he did not use oil or had any compression problems. I also used royal purple in my se and right after noticied an increase in oil pressure and the engine quieted way down. I also was a service manager for many years at an german repair facility which we exclusively ran castrol 20w50 in most of out vehicles
which some had an excess of 400k on them with no engine problems. The key is use a high
quaility oil filter, change regular oil every 3k, and synthetic no more than 7500 miles. Keep
the engine in tune and make sure the filter is clean, remember these all affect oil quality.
It is true that if you have questionable sealing on your engine that it will leak more with a
synthetic oil. Synthetics offer better guard against breakdown and are very beneficial if you do not drive your vehicle on a regular basis, prevents excessive contamination due to condensation in your oil pan. The oil base does not breakdown in oil, it is the additives that
make it a multi-grade, non-foaming, anti corrosive properties that do. Now that i have stated all this i need to eat, i have used up my last two brain cells. rx7doctor
