oil change

i went to kragen...what was so expensive? the oil?

 

try walmart, its probably cheaper

 

I was taught this growing up too, but I always wondered the following as I learned more about motor oil:

1. If the "5" in 5W-30 multi-vis oil indicates the cold flow viscosity, then doesn't that mean that the oil is actually "thinner" and therefore flows better at low temps?

2. After the engine has been off for awhile and the oil has had a chance to drain back into the oil pan, wouldn't it drain more completely?

Just some thoughts I've had - I've actually come to believe that it might be better to change oil on a cold engine, but I am no expert!

 

Hahaha!

I've been debating this for a while. I can see both sides of the issue, but I don't know enough to draw a conclusion. Debate time!

 

Take pancake syrup. Which is easier to pour, Cold Syrup or Hot Syrup?

I would have to go with hot. I do get the drain all the way to the bottom though...

 

Aha! Case closed.

 

^Yeah, he's a fart smeller, that Chris.
