Just picked up a really nice 2005 C55 AMG. 2 owner car with a 3" binder of every service record since new done by Mercedes. The car is stock aside from a big brake kit and some wheels. 133k miles. 0 issues. No leaks. 5.4L M113 v8. 722.6 transmission. From what I understand this a very...

Need a cheaper 5w30 for my rotary (series II 6 port rx8) that will get dumped every 3k miles as per manual and basically everyone else with a rotary. I want to keep this engine in good shape so that when I swap the car, I can sell my engine/trans package as a low miles unit with good...

Originally Posted by JoelB I like the rotary engine for the design and out of the box thinking. By why would anyone own a car that has so many caveats? I don't mean to knock the car at all, just curious. I mean it has a lot less moving parts than a piston engine and when well maintained, they...

Originally Posted by d00df00d Originally Posted by TinyVoices I likely will throw it on. The PO said the cat was removed at like 14k miles and never reinstalled so its likely that it'll last me a while before failing. I'll probably throw it back in considering its a quick and easy job. Maybe...

Originally Posted by d00df00d Originally Posted by TinyVoices I have the cat, I have just heard from all the forums that they fail easily and get blocked up and cause a ton of issues, hence everyone running cat deletes. If that isn't true, i'll throw it back in. Oh, it's true alright. But...

Originally Posted by d00df00d Few other points unrelated to oil: 1. You have a 6-port engine, not a 4-port. 2. The BHR coil "upgrade" isn't really an upgrade. The coils themselves last longer, but LS coils have been known to underperform the stock coils unless the ignition dwell times in the...

Originally Posted by d00df00d I had a 2011 R3 until just this past October. I researched the crap out of this and cut through a lot of BS. To make a long story short, there only seem to be two worthwhile engine oil options for this car: 1. Idemitsu Racing Rotary Engine Oil 10W-30 2. Any GF-5...

Originally Posted by rooflessVW I just mean the filter itself. K&N intakes are well designed, but the filters leave a lot to be desired. I put an aFe Pro Dry S on my K&N FIPK: Should I grab a big [censored] one like is on my car now or just any average sized one that fits in the box?

Originally Posted by rooflessVW Castrol GTX 10W-30. Ditch the K&N. Run it to redline frequently. I haven't got the stock airbox. The photo shows what my intake looks like (not my car). I see the 10w30 recommendation frequently. Would you go thicker in the summer for autocross/track days? I...

Originally Posted by Pelican Remember that rotaries burn oil, it's part of how they function and not a sign of wear unless it's extreme. I think they are also very picky as to what oil to use this is due to the seals at the apex. I'd check with a mazda dealer or inquire in a Mazda Forum No one...

Recently picked up a super low miles (37k) series 2 RX8. Bought the PO out of a loan he could no longer afford and got the car for about half its actual value. I own it outright. This is my first rotary car. The 2009+ rx8s are called the series 2 cars (series 1 being 2004 to 2008) because they...

I believe the one he/she is looking at has 96k miles on it.

Odd. Never heard of that happening and mine is rock steady at 130k miles. I guess there will always be one bad one here and there for every car.

Originally Posted By: SatinSilver Originally Posted By: danez_yoda Why would a 96K mile car need a new exhaust and Cat? Rust? if so check for other areas of rust as well. There's an exhaust gasket right in front of the cat that is a weak point and a common repair. A few bucks and it's fixed...

Originally Posted By: danez_yoda Why would a 96K mile car need a new exhaust and Cat? Rust? if so check for other areas of rust as well. Rear muffler section is connected to mid pipe with a type of v band clamp that is prone to rusting. It's common to see this area welded back together with a...

Originally Posted By: Kira Is yours an AWD? This one is. I'm told the AWD system is a little more forgiving of unmatched tires. I was so blown away by the cleanliness of the engine bay, I forgot to look for the familiar Toyota red coolant. The mechanic said he had to search for a replacement...

These are excellent cars that go forever. They are quite literally a hatchback corolla. Same car for the most part. I love ours. Incredible rear leg room for its size (easily seats 4 adults comfortably) and the hard plastic on the back of the rear seats means you basically have a pickup truck...
