Royal Purple Very impressed

I have an engineer working at my shop that did testing for FORD on longterm wear for Mobil1, Penzoil, and some other brands. Very intersting results from oil analysists to engine breakdowns from hundreds of hours on engine dynos...
We don't use anything but Mobil1 in any performance application, especially turbocharged ones. I've been inside enough turbos to see the difference.
To each their own however.

i use it in my motorcycle but that is due to the wet clutch and gearbox.
95% of rotary engines do not ever die due to lubrication caused failures(i would guess 4% of the lubrication failures are due to oil level run dry due to a failure in the delivery system), hell most of the time the bearings are in great condition and many rebuilders reuse the original bearings to run the engine for another 100k+.
i'll stick to my own thoughts on the subject and i doubt either of you will be able to sway that. last i knew my car was not driven in a lab also.

I dunno about you guys, but I run melted butter. It makes my exhaust smell like popcorn 
I say run the least expensive oil you can and you more frequent changes, its still cheaper than nearly $20/litre for some synthetics.
But some people prefer the peace of mind. Although I have no doubt that a synthetic won't break down as easily as straight conventional, but I changeit too frequently to care anyways

thats the thing, most engine oils still have plenty of life left even after 3k miles, the problem is the oil is filled with carbon and deposits which is why it gets changed regularly. if you could run a synthetic for 10k miles then i would say the offset may be worth it but after 10k miles the oil would be filthy and so would the internals of your engine.

Well I like the added peace of mind, I don’t see it as being a waste of money, plus I can guarantee that synthetic oil will perform better in turbo applications. Ok, maybe I can’t guarantee but from what I’ve read it should.

Well in the 7 every 3k or sooner but in the Audi every 5k. The factory service interval for the Audi is 10k. The dealer changes it for free every 10k, I just change it myself in between at 5k intervals.
On a side note my wife’s Honda Pilot uses 5w20 oil…..that’s like water.
I don't have a boat?......haha!

As for increasing the oil change interval, don't you still change the oil filter every 3k?

Are royal purple products that hard to find? Where i shop they keep the entire line fully stocked at all times. I also asked them to bring in some lucas oil products and some MMO. And sure enought the next week it was all there, just from me "the rotary guy".
And I don't use synthetics in my motor. But I've been know to use some lucas oil stabilizer from time to time.

As for royal purple. you can find it in lots of places around here, be we are the ricer ******* capital of the south. I mentioned it to my local o-rielly's and they carry it now, but you can get it cheaper online. I think the NAPA here carries it too, as well as several of the ricer shops. I think there's even an oil change place that carries it.
I actually found a place online a few years ago where I could get it for 5.50 a quart, but I'm pretty sure RP has raised its prices since then. Cheapest I saw when I looked earlier today was 6.70.

My wifes car uses 5-20. I hate it because I can't see it on the dipstick to see how much I need to add.
And wow, I never would have suspected that RE Amaskdlhag (sp) would have his own damn oil. That just blows my mind. Its probably rebadged idematsu rotary oil, or whatever.

having been an auto mechanic for 15 years and run my own shops i would hardly call uneducated on the subject.

I wonder when the #-10 oils are going to start coming out. Motors these days are getting tighter and tighter.

Oil has nothing to do with how the engine does or does not vibrate.
If your engine is vibrating, you either have nasty imbalance problems or your mounts are loose or broken.
"Trans as much heat"?
What does that mean?
The engine runs cooler?
How much?
What gauges tell you so?
What is the difference?
Under what conditions?
Yeah, I thought so...
