Michael Kirn uses Lucas Heavy Duty Oil Stabilizer for 1967 Bonneville

I started using your oil stabilizer in my 1967 Bonneville and still no rear seal leak. My 2002 trans-am developed noisy lifters at about 15,000 miles and GM claims this is "normal" and acceptable, refusing to do anything about it and further advising that Mobil 1 15w50 was too heavy. Possibly causing the problem. I went all the way to 0w30 Mobil 1 with no change other than worrying me to death since Florida is hot. I went back to 15w50 and added a quart of oil stabilizer. NO MORE NOISE. This stuff is so good i may start putting it on my breakfast cereal.
