I thought I bought a Toyota not a BMW….

Considering it was 9:30 at night and the wife had to be at work the next morning and so did I. I filled it back up and took a hit on the chin.
The next day I called the guy I buy tires from and told him what was going on. He said bring it by he will change the filter himself and not over tighten anything. And probably wouldn’t lose that much oil just to bring a little extra. Sure enough I picked it up after work and he tossed me the keys and said it was on the house. Pays off to be loyal to a small town tire business.
I had already warned him of the missing 10mm bolts and the two cross threaded 12mm.

 

Moral of the story buy the better tool and put a bigger bar on it. From what I am reading

 

This is exactly why you should do your own oil change. It is not an easy 5 min job. and I do not trust anyone doing it but myself..
empty oil pan, then once you remove the front skid. use the Motiv X to loosen filter (no need to remove the bottom nut to drain it). slowly release filter and dump oil from it.
put new filter and o-ring with fresh oil. and tighten to only 25NM (do not over tighten). done.......fill oil and check.
It is not easy but not hard as well...

 

Are the skid plates’ bolts easily stripped? Design issues ?

 

Air tools.

 

The battery operated 18VDC are even more torquey then pneumatics .

 

Yeah but air tools are used throughout the car..

are these skid threads especially weak or something?

 

I don't think so. I think people are less likely to get them started right because of how they're buried and because you're supporting the weight of the skid while trying to get them in. How many Jiffy Lube guys start them all by hand to feel that the threads are properly engaged? Or do they just load them in the socket, point up, and pull the trigger?
