Motor oil & more...
What kind of motor oil are you guys/gals using, and what'* the difference in brands & weights?
Also, I was in an auto store a few days ago and noticed two cars (1997 Bonneville & 1998 Buick LeSabre) both with 3800 Gen II motors. The LeSabre had a junkyard transmission in it; I assume the other went dead. The Bonneville (owned by a lady looking to be around 50+ years old) said she just had her transmission rebuilt a few months ago at about 90K miles on the car.
My question is: Is this common problem on these transmissions?
What type of trans is in these cars. The motors were not Supercharged.
Reason for my concern is that I purchased an L67 (Supercharged) motor & trans 4t65e w/ 67K miles on them from a 1997 Bonneville SSEI for my LeSabre T-Type.
Thanks in advance,
