New RX8 Owner
 

Just picked up an 05 RX8 GT AT in Ontario last Tuesday. Drove it back to Saskatoon Saskatchewan 3200 kms (2000 miles). Great little machine. Has 11500kms on it or 72000 miles. Runs really strong and only used about 1/4 of a quart of oil in that distance. Mileage is as others have stated. I notice a lot of rear differential noise. Is this normal or not. It could also be a rear wheel bearing but it is hard to pinpoint. Looking froward to better weather and driving it more.

Welcome to the addiction! Post some pics of your ride when you get a chance :)

Hello..eliminate the typical exhaust hanger noise first and then see if it is truely the differential. Without knowing what sound your hearing, I am just pointing out what is common on the 8's. Also, look into seeing (if you can), when was the last time the coil packs and spark plugs/wires were changed. Then decide if you want to use the OEM coil packs or go with the GM coil packs from the LSx engines and use the wire adapater kit that is out there or a turnkey solution from someone like Black Halo Racing. Just from one new owner to another!

There is a lot of rollover noise in the transmissions as well....

The differentials are quite robust..not a lot of problems with them usually. Might want to change the tranny and diff oil though...likely due for it

Redline is good...just stay away from RP in the transmission...doesn't seem to like it :)

Welcome and post pics.

Already did the engine and diff oil change. I am going to do the automatic when I get some more time. I pulled the oil pan off to investigate where the foamy oil problem is. I am no longer concerned as it is just a small amouint of foam that sits just below the dipstick tube where it is the coolest. Just happens the stick runs through the foam when you are checking the oil and it looks bad. hardly any foam there at all.

I haven't read anything about exhaust hanger noise. I will do a search and see if there is any info on it. Thanks

Welcome fellow Saskatoon owner. Mines a 07 Rx-8. Have fun today in the snow storm. Only got my car stuck once so far.

Congrats and post pics.
