Interesting. Please define "worked great". What were the problems and what did it fix?rwess said:I Have A 98 Sls With 101000 On Her. I Used Engine Restore On Any Car That I Had With High Miles Before And It Worked Great. I Was Wonder If I Can Use It On A Northstar?

I dont think i would use any in the northstar though, seeing how the liners last some 300k miles and all.
Its really goopy stuff and may turn you oil into sludge.
