Re: Advice on oil type sought
I've been using only Chevron Delo 15-40 in my Universal 5432 for 6 years and over 500 hours. I would choose it over other options, and especially over a straight 30 weight. Like was said here, if they had 15-40 back in the day they would have recommended it.
Fun story: Back in the early 80's I was given a VW bug that had been running only 80 W aircraft engine oil for over 100,000 miles. The original owner swore by it. Never leaked, never smoke, nothing. I thought, hell, how can that be? Won't flow right in the passages and such. Started using "normal" 30 weight and of course, starting leaking and burning oil. Went back to 80 W and had no problems until I sold the car years later.
OLD trick for selling cars with worn engines. The basic philosophy behind STP.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
