My female friend (previous car was a purple civic that was totally devastated from neglect, moreso than ANY other civic I ever saw, every panel dented, broken trim and lights, needed to add 20w-50 3 quarts at a time when I saw her, dirty windows and interior) her husband got her a new BMW on lease. She drive short trips on Boston, a tough circuit. When in town I offered to check out teh BMW and even use my extractor to change the oil to anything they wanted, even free Delo 30, to get them to the next service. Husband declined, citing that he's a lawyer and if anything goes wrong, he'll sue. Well, the car was 2 years old with like 18k....still on original oil.
My advice was to get a dealer synth change every fall and let me chaneg it in the summer with 15w-40 to keep it fresh. No thanks was the reply....I dunno if they actually said thanks.
