Oh what a goose I am!
So I see a great buy on 10w 30 at the store and grab a case...changed the oil in my NEW 235. This is the the first change after 300 miles...and I notice I grabbed a case of 5w 20!!!! Oh good gravy. I know it won't do any harm but should I run it or drain it ASAP?

BTW it is winter here.

You might see a little more oil usage because of the thinner oil. I'd keep a closer eye on the oil level until the next change. I don't see a reason to panic & drain it.

TT,

The oil will lubricate, and it won't kill the new engine. I would consider it on the shy side unless it gets quite cold in Maryland.

I have actually never seen 5w-20...maybe they don't market it in the warmer areas.

If it were my rig, I would run the 5w-20 for as few miles as my pocketbook could stand, then change it. With a new engine, there are bound to be goodies in the oil, and a quick change wouldn't hurt anything.

Did the rebuilder recommend the 10w-30 oil? What is an average temperature in your area.

We sell the 5-20 here in central Texas.

Most of the newer F#$%s reccomend this oil in their engines.

Should be okay, just keep an eye on the fill level.

Use that oil as a kind of a rinse or flush oil. I wouldn't waste it, I would drive it while it's cold out and do a low mileage oil change in the spring.

Hi Stuart, you can get 0w-20 for the really tight tolerance engines. That be some thin stuff.

A lot of the newer vehicles are now going to 5W-20. My 2005 Dodge Magnum calls for 5W-20 and the MDS system will not function properly if you put a heavier oil.

My Honda uses 5w-20 in the crankcase and 10w-40 in the transmission. It's like water. The VTEC doesn't work right without it.

216's were supposed to use SAE20 oil, I wonder how well 5w-20 would work in one?

I suspect other than a bit of extra lifter noise and slightly low oil pressure a 235 will be fine. The main bearings are so big they probably will be fine. You may burn or leak more of it though.
