DIY Oil change with Castrol Edge full synthetic 0W-20 oil, Mazda filter.
Last oil change was at dealer when they had vehicle to check for warranty issues.
The Drain plug was welded on/overtorqued from dealer. Was able to get off with alot of leverage. At the point you need to run a pipe over your breaker bar, means the plug was over-torqued.
Luckily the oil pan does not appear to be cracked. But this is just one of many reasons, I prefer to DIY or have my local mechanic work on my vehicle.
Also, sent oil sample to Blackstone as questionable as to what oil they used.
Am thinking they might have used either a substandard dino oil or blended barrel oil instead of full synthetic. Will be interesting to see the UOA results.
It's a miracle that the plug wasn't stripped being THAT tight! Those techs who use air tools to tighten the drain plugs gotta be some kind of stupid!
