5-20 weight oil - what do do with it

[woodlandfarms]

My father has moved from the farm into town, and dumped a bunch of newly purchased oil at my doorstep. (not new enough to return). There are 8 bottles of Castrol 5-20. I assume this is for the honda or something. I would assume that my tractor, which takes 10-40 for Hydraulics, could NOT use this, although it would be nice if it could.

So, at the risk of being niave. I tihnk I have a bunch of 5-20 that has no purpose, other than maybe putting it in my diesel tank, right? I have nothing that I know of that would use this and unless I can mix it in with my Hydrualic oil I seen no future for it.

If it is 5W20 it's good for most modern gas engines like my '07 F150.

Ford and most of the imports have speced 5W20 since about 2001. Hold on to it, you will have something that needs it sooner or later.

Worst case you can use it as an engine flush if you don't have a use for it.

Drain your engine oil, then fill the engine with the oil run the engine for a few minutes then drain it out. You should have a spotless engine inside when you put the real stuff in.

Use it for bar oil in your chain saw

Takes a **** of a lot more than that to make an engine "spotless".

Don't put that oil in anything that wasn't spec'ed from the factory for it, yes, newer fords spec if for their V8s, but that doesn't mean it will work well in an old Ford V8.

The only real good use for 5w20 is foreign cars or other things you don't give a crap about. It will produce more wear in most engines than a 30w will. The only reason this oil was ever invented was to make the EPA happy - not because it does anything good for your engine.

It is basically "watered down" oil. A few steps away from using WD-40 in your crankcase.

Hmmm.. couldn't be that Ford, Mazda or Honda, might have conducted lab engine tests for millions of running miles, costing millions of dollars, on their engines with design spec tolerances precisely for a 5w-20.
Naw, that couldn't be it. Those fools!!

Yeah, like I said, only for engines designed and spec'ed for it. It will ruin anything else. The only reason those manufacturers bothered to come up with a new oil was to make the government happy, not 'cause it works better.

Except that's not at all what you said.

The OP simply asked what to do with his freeby oil. He also did not state specifically whether it was semi-syn, or pure syn, or dino. Without knowing, the recommendation of what to do is harder.

I cannot speak for the Honda spec today, as our CR-V is 11 years old, with 140K miles and the 5w-20 wasn't specified then.

My '05 Ford truck is specified 5w-20, but Ford insists on at least semi-syn with full syn also recommended. I sense the synthetics and other additive packages strengthen that stuff pretty good at the molecule level.

I would only be guessing what the other OEM's who spec 5w-20 allow the use of 5w-20 dino. I just don't know.
