how many miles on your engines now and previous if any
 

how many miles do you guys get on your engines before the go or current. i have 105000 miles on mine. I am trying to figure out the normal life on these engines and also premature ending of these machines.

My first engine went with 30k miles on it
My Second engine went with 35k miles on it 65k on the car.
My third engine now has 15k on it ans still going strong and premixing

Dunno, have read the oil consumption kinda is like a prevenitive maintenance program for the RX8. Sure it uses more than the piston engine, but is replenishing fresh oil between oil and filter changes. For more added comfort us a pre/mix and report back after 200,000 miles....

Do you think the oil weight played a major role in those failed engines.

I do not have the slightest idea. Never saw inside the engines. The first engine when it was warmed up and driven for a while the apex seal did not seal right and the second engine the rear rotor lost all compression.

lol, thats retarded. Maybe you just got unlucky and the engines were deffective.

I am hoping so. When the dealer installed the first one it took 2 months at Grecco Mazda . The engine i have now only took 2 days at Wayne Mazda, go figure. I hope the first too were deffective.
