Hey fellas. Have my '02 Bugeye wagon giving me a weird issue I have yet to solve. I recently changed from Mobil 1 5000 (conventional) to Castrol GTX Hi-Mileage (85k on her so far.) I've only ever used 5w-30 in her, and recently I've gotten this issue. Every now and then, not even every day, I notice a slight oil burn smell, but don't see smoke or steam anywhere. I checked this morning, and with around 1000mi on this change, I'm already down to just above half full in the pan.
Now, I've also noticed with the colder weather here in NJ, I get a slight squeaking noise. It sounds almost identical to old belt slippage. The noise only happens with the clutch engaged, in or out of gear. Press the clutch, noise goes away. I don't think it's the belt due to the fact that it's not an obnoxiously loud squeal.
Wondering if anyone ever had the same issue, and if you have any ideas. I'm at wits end and I'd rather not have something small to into catastrophic failure.
