I was in a Tractor Supply store yesterday looking around during lunch and came across some motor oil on clearance for $4.99. It's a 2 gallon jug of "standard non-detergent motor oil, SAE 20W-20". I thought I had found a really good deal until I picked it up and started reading on the back. It said it was NOT recommended as an oil that requires additives, and was not recommended for use in automobile or truck engines. I have two questions........
1. What is this oil good for?
2. Is there any place in or on my old truck I can use this oil?
Many thanks!
