Id recommend adding pre-mix with every, or every other fillup (do some research on the forum about it as far as how much to add, etc.) Other than that id stay away from crazy additives..i run some water wetter or something in my radiator in hot weather, and get some seafoam in the engine every 15k or so. Get a spray bottle and squirt seafoam right in the two small nipples you can see on the exhaust manifold coming off the engine to keep that carbon out. Big killers are Oil not lubricating the engine well enough, (use thicker oil, premix, Sohn adapter). and carbon build up in the engine. Make sure to stick your AT in manual mode and redline it every day/other day. All this has been keeping my new engine strong for the past 50k or so. Just my recommendation on things...

40th anniversary Edition
Hey I have owned seven different rotary Mazdas since 1973, and raced three of them. I now have a 2008 40th Anniversary Edition RX8. In all my rotaries, street and race, i have used a premix solution. My favorite one, which I have used with success on street and track, and am using in my RX8 is Pettit Racing's Protek-R Synthetic Fuel Lubricant (made for rotaries) www.pettitracing.com PN#0100-4. I put in about 4 oz. per tankful for normal fun driving, and more for racing .
In all my years and easily a million rotary miles driven, I have NEVER had an engine failure, ever, even in my racing. Premix is one of the keys.

64k miles total
32k on first motor (stall/no start)
14k on second motor (oil leak)
third motor going strong since.
I have been hesitant to try premix, but may give it a shot. I need this 04 to make it to 2014 so I can get a next gen RX

40th anniversary Edition
Man if you want to help your engine to last, you need premix, whether the Pettit racing brand or some other brand. If you hesitate, your engine will suffer, and you may be replacing another one. Rotaries need this for longevity, I know this from nearly 40 yrs of rotaries. I have owned an RX3, two RX4s (both sedan and coupe, raced the modified coupe), all three generations of RX7; first gen RX7 (later modified and raced), second gen RX7 turbo II (later modified and raced), third gen RX7 FD Twin-Turbo (later modified), and now both a 40th Anniversary RX8 and a Mazdaspeed3 GT (both fitted with Mazdaspeed Cold Air Intakes). I have NEVER had a rotary engine failure on seven different rotary cars since 1973, and premix is an essential part of proper upkeep to make the rotary last.
Just do it !

40th anniversary Edition
After nearly 40 years and over a million total rotary miles on the street and the track, luck of the draw has NOTHING to do with it. It's all about knowing how to care for your rotary engine. Period !

Soooo finally hit the 100k club 
No new problems other than the same oil leak. I'll dig in there one of these days but the cabin smell at stops doesn't bother me too much. The cat is finally dying(barely passed smog) and the tranny is starting to get a little weak. Other than that she still runs like a champ. Here's the pudding

Help a girl get hers running several years ago.
It was an 04 with 140k(original) miles on it.
The car was severely neglected, but another member and I got it running and all was good until she totaled it about two weeks after we fixed it.
I'll have to go find the thread to insure I got that mileage right.
Yup..................had over 140k on it, was one of my better moments helping someone out that really needed it. Takes till about page 2 or 3 before I really start to get involved though. https://www.rx8club.com/rx-8-discussion-3/rx8-sale-needs-new-motor-repaired-update-163605/
BTW.............do some searches as this is infact a repost, there are other threads high mileage threads.

86k on first and only motor. Seems to still run strong for an automatic. Full stock, no mods yet.
Used to run any premium gas that was cheaper, now run nothing but Shell vPower (93). That has made a huge difference in how this car runs. I would not believed anyone who had told me otherwise.
Anyway, I get 24-25mpg cruising on hiways +70mph (minimum LOL) and usually 20-21 for my daily commute.

Just hit 118k today, still running strong but I did realize I have a bit more of a smell of burnt carbon when I get up to 6-7k. Time for an oil change btw
