HI to all,
I have 2 old cars since new, for 30 years, in my family. A 1976 Buick Electra 225 LTD, 455-V8, 104000 miles. Uses 1qt. of 20w50, Castrol GTX, every 500-600 miles, throughout it's history from new. Next, 1979 BMW 733i 3.2 I6, 205000 miles, 15w40 Shell Rotella T, in this last change, but have used a good 10w30 oil, used 1 qt. in 3000 miles or due at change time, of whatever was on sale at Murray's, in Ann Arbor, MI. when I could do my own servicing. I am in the Michigan Masonic Home, in Alma, and have found a great local MECHANIC, to help me keep my old cars alive. I trust them to go anywhere at anytime, after getting them back in shape. I was paralyzed for 2 years and couldn't drive or walk. Doing better, but not without a wheelchair and walker for me. The cars are swell, better than I thought.
I am doing a MMO treatment on both cars, which I posted in the additives section of the forum and have had a nice reply from Doug Hillary, from OZ, on his 928S4 Porsche, great car!
I need your thinking on what oil to use with my old Buick and BMW, when I am done with the MMO treatment.
I decided that Mobil 1 5w40 truck&suv oil, would be ideal for both cars. The question remains will the Buick, guzzzle this oil and start popping leaks on me? The Buick has been using Kendall GT1 20w50, most of it's life with a case of Castrol 20w50 GTX, on occaision. The BMW has Shell Rotella T 15w40, and really likes this oil. It hasn't used enough to add before the MMO treatment.
Other chuices are Mobil Delvac 1300 15w40, Shell Rotella T 15w40 or 5w40 Synthetic. Depends on what happens with consumption and the costs at the oil change places. There is a Wal-Mart, here so I can buy the Mobil 1 5w40 t&suv, 5qt. for under $20. OK, what do you think?
