I've been interested in buying this silver 2005 RX-8 with around 80,000 miles on it for a few weeks now.
The seller claimed to me that the car goes in for regular maintenance, and that last month the car "passed" its compression test.
When pressed further for actual numbers she called her dealer and they gave her a flat number of 7.5 with no units. I told her I needed to know both compression ratios for each rotor in order to feel comfortable buying the car.
Instead of asking the dealership's service technician herself, she gave me his number and I talked to him today. He is convinced that only one number is needed with Mazda's special compression test kit for rotary engines. He said that there is no need for two numbers, even though I know that is blatantly false.
I know what ranges are acceptable for compression ratios on the 8, but I was just curious if any of you out there have had similar experiences. Is the dealer averaging the two rotors? Is there some test kit that isn't the usual one i've dealt with /seen that only gives one read?
Thanks guys. I searched for this topic and did not find any threads describing this experience I've had. If there is one, I'll delete this thread and pose my questions there. Thanks again for being such an insightful community.
