To rebuild or not rebuild, that's the question!

Tirebird,

------Can you give us your reasoning for using Mobil 1???
------I had an oil consumption and lifter noise problem with the crate 502 in my Suburban with Mobil 1. A very good local engine builder told me to switch to 15/40 good quality regular oil. This quieted down the lifters a ton and cut my oil usage in half. Oh yah, I have just over 130,000 miles on the motor now, and it uses a quart per thou. It has also surprized a few 5-liter Mustangs and gets right around 17 miles to the gallon without trailer. Thats about 2 miles to the gallon better than the 454 I took out. There was quite a bit of computer re-programming involved in getting this mileage figure.........Bill S
