"It's the Stingy Person who Spends the Most."

Dear Car Talk | Oct 01, 1991
Dear Tom and Ray:
Hugh
RAY: Hugh, we can tell you're a card carrying cheapskate. Don't you know the famous Click and Clack axiom? "It's the Stingy Person who Spends the Most." You can probably get by with SF, but why take a chance on damaging your brand new engine just to save a few bucks on oil?
TOM: SF and SG are ratings for engine oils. The second letter measures, among other things, the oil's ability to lubricate the engine, neutralize acids, and hold contaminants in suspension. The later the second letter is in the alphabet, the better the oil. SG is currently the highest rated oil you can buy.
RAY: They're hesitant to improve the oil any more, because then they'll have to go to the SH rating, and they're fully aware of the implication of that.
TOM: Don't chance it, Hugh. Put a bow around that case of SF and give it to a neighbor with a lawnmower.
