Another reason NOT to go to Jiffy Lube
All interesting stuff. Costco used to do oil changes and I let them do one in my 1986 Toyota pickup one weekend when I was in a hurry. On my way back to Lake Havasu I started smelling oil and pulled over. The front crank seal was blown and the engine was covered in oil. The dipstick showed oil up until about 3/4” of an inch below the top of the tube. Later on, they bent the skid plate on my 1990 Bronco when changing the tires. I watched them lifting the car on the plate, not the frame rails and ran over and complained to the manager. He stopped the tech and walked away, and the tech immediately did it again. Finally, I had to show him how to do. Costco bought me a skid plate.
One more thing, on additives. Has anyone tried BG lubricants? Their rep used to do the motor without oil demonstration. He came by the Kawasaki shop I worked at in Phoenix in 1976-78 and we started using the stuff. When we added it to a KZ900/1000 we would have to turn the idle down when the motor warmed up the first time, and that’s where we would leave it. The only problem we had was with the clutches in some of the motors we built with big-bore kits, big cams and carbs. We would save the “BG nickels” that came in the cams and turn them for jackets, etc.
