Hi,
I'm looking for the "modern equivalents" of the liquids mentioned in my 1967 Owners Manual, to give my LeSabre Coupe a nice service.
Engine oil (340-2):
"SAE 10W-30 up to 5W-20, depending on lowest anticipated (outside) temperture". - What are you using? Is selecting a good 5W-30 fully synthetic oil a good idea or do you rather chose a "special vintage car" mineral oil instead?
Coolant:
"GM Spec. 1899-M" - Right now the system is filled with a translucent "neon green" coolant. Any idea what this might be?
Power steering:
"Buick power steering gear fluid"...whats the best modern replacement?
ATF (ST300):
"Special Buick Transmission oil or AQ-ATF"...what to get these days?
Real axle/diff:
"SAE 80 or 90 multipurpose gear lube, GM Part No. 1050081"...can you just use a 80W-90 (GL5) oil here?
Thanks for any advice!
Cheers,
Harry
