Alright, I changed the oil today. She's a 1989 Mazda MX-6 GT (turbo motor, F2T) with 194K (on the original clutch too!). I'm the original owner. She's always run great, unbelievably dependable. The only non-synthetic she ever had before today was what Mazda put in there. But for several years I lived very close to work (3 miles) so those were some hard years on her. So now she has Delo 400 15w40 and a bottle of Auto-Rx, with an oversized filter (Purolator L20253, originally for the Corvette ZR-1 engine) to catch all the gunk. Here's hoping for a good cleaning! I'm planning to use the Seal Rejuvenation regimen (dino in both cleansing cycles as well as the rinse cycles), but I do plan to return to synthetic once this is over. I'm a Mobil 1 guy, usually 15W-50. I did run Syntec for a while, but when I learned that it was cracked I felt misled/cheated, so it was back to Mobil 1.
Anyway, I'll give updates as pertinent throughout the regimen. I'm believing you guys!!!
