Motul 710 is surely a good oil, I use it for Sohn and premix (~250 ml / 50 liters).

If you're running on the updated pcm flashes 250g per fill-up should be enough. Reaching 200.000km on a stock renesis is not a problem if you do the regular maintenance wisely. Keep your ignition system in good running order( replace your spark plugs every 30.000km or so, upgrade or replace the stock coils etc), make sure that your catalytic converter is fine and that the OMP is properly working.
That's all you need to do, going above 6000rpm will prevent the intake valves from sticking so just have fun with your car!

Its a general rule around here that "a redline a day keeps the carbon away". If you always baby your engine when its warmed up then you will most likely not reach that 200k km you want. It will be hard to reach anyway, but not touching the top 3k rpm will most likely make it harder.

Now whether that is 100% or not I do not know, but I believe it. I have personally seen someone kill their rx8 in less than 20k miles from brand new. Their wife mostly drove it and she always kept the rpm as low as she could when driving it.

Look around on the forum, its been discussed to death and I'm sure there are people on both sides of the fence.

welp, finally ran out of the FP+ a few weeks ago, and after experiencing no noticeable ill effects, and nothing to be concerned about in regards to contamination (per BSL), I ordered a nice big jug of it from the guys at LCD. Looks like they redesigned their plastic a bit as before it would start to cave in on itself from whatever affect the liquid has on the plastic they used to use lol.

I buy Idemitsu by the case (lasts about 18 months for me) locally at MazdaTrix. 1 case @ $67 = 1 quart @ $5.58.

If you like using Lucas semi-syn, one way to get it cheaper is to order the gallon size container at O'Reilly's. It's only $26.99 which comes out to a $6.75 a quart.

Shipping is expensive so it is best to call your local O'Reilly's, have them order it, then pick it up when it arrives.

I put on the BHR ign at 23k miles and left original plugs in.

My reasoning is that if the ign is firing right, it'll burn deposits off.

So at 28k miles I take out a leading plug thinking I'll put in new ones.

The gas had a healthy 8oz per 12 gal premix on Mobil 2T (discontinued), but the plug had no black carbon, just a little of the usual tan.

I have a 6spd auto that revs less than the manual, and I plan to keep running them.

My point here is that after running Mobil 1 0w40, and Mobil 2t ( pib type) my plugs look cleaner than on any car I've had.

You can believe it or not, you can wait for somebody other than rotary experts Racing Beat and Pettit Racing who have extensively tested premix and gotten great results.

I know from nearly forty years of rotary experience, that is all I need. You can waffle about it,while I will continue to use it and have long lasting trouble free life with my rotary engines, while I read about blown and premature dead rotary engines.
im getting my rx8 friday i like synthetic oil.. and im going premix cuz if i rebuilt engine i want to run for years.. my previous rotaries are still running great with synthetic after yearsssss driving them . but I never done premix Im guessing is good my previous rotaries have been CARB, so MPG I never cared for since I knew what I was getting my self in yearsss ago, rotary dont go together with saving gas ,lol

i have been on both sides of this..

if you dont track your car, and your car burns oil / omp is working fine. just never let your tank go below 1/3 of a tank and you will be fine.

if you track your car i would find a mix that works with you.. and never let the pump get below 1/3 a tank.

i think lots of these pump go out early, or very early by running them down to the yellow light or more.

i am guilty of that..

i find for track events that one oz per gal seems perfect, and i have a car that does not use a lot of oil...

make sure if you are going to premix, you mix it before you dump it in the tank..

beers

Realize that plug replacement is based just as much (if not more) on electrode erosion / gap. If the gap is worn beyond the specified range, the plugs should be replaced (re-gapping iridium plugs is not recommended).

I still have almost 2 gallons left when the light comes on, and I have often run it down to this level (I usually fill-up when it's down to 1/8 tank). No problems with fuel delivery or the pump in 50,000 miles, so I don't consider this an issue.

Also, I think premixing the premix before adding it to the tank is a bit of overkill. I've been premixing since the car was new by just adding it to the tank before each fillup - no issues.

He is just trying to prevent any confusion from people who add premix after they are done filling the tank. Again, not a huge deal as daily driving will mix up the solution, but the goal here is to have an even mixture righto ff the bat.

I have seen the low fuel light so many times with this car. I know all the reasons they say not to run on low fuel, gunk in the tank, premix gunk possible also, and the fuel not cooling/lubing the pump properly when low. It just has never caused me any issues in any car.

I ALWAYS run it into the yellow and below the empty mark . Then I dump in the premix and fill her up .
Been doing this for 5 years now.

Hi Swoope
That's the way I do it. I prefill a bunch of these (similar anyway) 8 oz bottles with Idemitsu and keep a couple in the trunk at all times. I use Idemitsu in the SOHN reservoir and in the tank.

The lucas semi-syn 2 stroke oil has markings on the side, as long as your filling the tank when you first open the bottle its easy. The markings start at 24 ounces so just pour until it hits there and thats 8 ounces in the tank. Having little 8 oz bottles seems like the way to go though.

Isn't 8 ounces a bit much for UCL?

Those are the bottles LCD, Inc. sells and sometimes give out free with orders. FWIW FP60 has a 100C viscosity of 9.25CST making it a good premix candidate especially give its cleaning ability. Its flash point is 385F COC method.

Amsoil Saber I like better with its 13.xxCST at 100C as far as protection. From what I’m getting after going over and over the UOA consolidated analysis I did heavier viscosity oil injected is reducing the Chrome wear so reading between those lines a good, stable premix makes sense.

I did not want to keep typing "lucas semi-syn 2 stroke" so I just went with lucas, no clue on lucas UCL I never used that.
