Should I slob it?

[goixiz]

Valentines day Pink bottle special
I was not convinced that it should be $1.99 so i called a round and one store had just marked theirs down to $1.00 but only had 2 and 15 miles away so i called the one 2 miles away where they had theirs for $1.99 that i bought a few a couple of days ago and they said they just got 2 boxes and and will match the price of the other store

Now I have 2 boxes and 1 bottle in the garage

In a 1978 engine, I would not hesitate to put in the whole bottle of SLOB.

how about in a 92 Galant SOHC 2.0 with 140k on the clock?
the only O2 sensor she has is right on the manifold...not sure if that matters or anyone cares, but thought i'd say it.

BTW, why does the SLOB bottle say it's for 5W-30 and up?
why not 5W-20?
