I thought I'd write a plug for these guys. I too am one of those picky retentive guys who loves my truck, has put thousands into it and trusts no one with it. These guys I will go to however.
Years ago I had a car I was taking to "something" Lube. I had a few bad experiences with them but overlooked them as it was the free oil change after the fifth one I wanted. Until they tried to sell me an oil plug for $20 that they had wrecked. I had gone to them every 5000K for approx 320,000kms. They had been using a pipe wrench on the nut instead of the proper socket wrench. I told the manager I had quite a long history with them and I wasnt paying for a part they stripped. He was content to tell me that it just happens. I said i'm not coming here anymore.
Thats when i went to Great Canadian by Walnut Grove. They actually told me the plug was in bad shape too and asked if I was wanting it replaced. I asked how much. The response was are you going to come back here? I said sure. They said ok, we will throw it in for free! Imagine that a first timer and giving me the plug. I have been loyal to them now for thousands of kms... all for a $20 plug. This location will not upsell you additives you do not need etc. The owner I have chatted with several times and commented on his staff professionalism and giving me what my car needs not selling me stuff I dont need. Thats what keeps me coming back.
I just bought a new 383 stroker for my lifted truck and run amsoil in it now. Who else am I going to trust with an engine I just paid $7000 for? These guys of course!
