I change every 6 months or 5k miles, whichever comes first. I’m about to do my break in oil change at 1500 miles. First time I’ll have my black wing up on stands….
That is gorgeous! Good on you for keeping these classics alive.I had my 5BW done at the dealer at 1450 miles. 1st one is complimentary anyway. I just spent $11,000 getting my 1967 Cadillac deville convertible 429 ci engine rebuilt. I had to source many parts that needed replacement and are not cheap. The car has 200,000 miles on it and my Dad bought it brand new in 1967. I took it when I was 12 years old because he said he was gonna junk it. I'm 58 now and still keep it nice. My engine builder had me bring it back for a 1000 mile check up and break in oil change. The rear main seal is leaking ,even after 5 attempts with new seals. I may need to source a new/used crankshaft. He said that these are man-made machines that metal rubs metal , no matter what the factory says. He says that many of the engines he rebuilds are because they go too long without an oil change "as the owner manuals recommend" now. Its better to change the oil every 3-5000 miles just to have a peace of mind. Oil changes cost less than an engine rebuild.
The rear diff fluid is supposed to be changed after the first track day.So just pondering. On the M cars, first mandatory break in oil change is 1500 miles but there is something else I don’t see here. The rear diff for M cars also get a fluid change. No rear diff for a caddy?
