I change my oil religiously every 3k miles. In fact I just changed it 1k miles ago. I was having a misfire in cylinder 1. Found out it was a fouled plug. When I change them I noticed there was oil in the cylinder. I put the new plugs in and everything thing seemed fine. No misfires. Drove about 75 miles and had some spirited runs and started seeing a lot of smoke at higher revs. I parked the car thinking it was just clearing out whatever was in there. Today when I took it out it was smoking really bad. Especially when I got on it. Also a lot of backfire. It’s not overheating or losing coolant. It’s actually running really strong. When I got home I decided to check the oil and it’s a good thing I did. It was almost nonexistent. When I checked the dipstick I could see a little oil on the end. I’m using HKS 45. The car is full bolt on plus tuned. I’ve had it fbo and tuned for almost 2 years with no issues other than a few misfires here and there. Any input would be appreciated.
