I know my four cycle lawn and garden stuff all seems to run on 30
weight oil including that monster Ariens snowblower I have.

I remember going to AutoZone looking for 30W ND and the guy at the counter
had never heard of it.

Why does that not surprize me.

What the hell is a snowblower? 8)

No. It's used in the hydraulic water pump on pressure washers.

Ok, boats... I'm retrofitting my 1976 Chrysler 75hp outboard with a
used tilt/trim unit. Hooked it all up, figured out the hydraulic
lines, followed the procedure... Filled it with 30 w non-detergent
motor oil. I run the unit up and down several times, all seems to be
working OK once the cylinders filled with oil and purged the air.
Opened the reservoir to check the level, a bunch of foam spilled out.
Drained the oil. Refilled. Ran it. Same result.
Am I doing something wrong? Is a certain amount of foaming normal?
Any suggestions? Experiences?
Thanks
30 weight motor oil? Um...no?

Get a couple of quarts of hydraulic oil.

Motor oil?

A lot of older tilt/trim units did in fact use 30W.

It's also used in air compressor pumps. Try Sears.

The hydraulic unit for my stabilizer system specifies 30wt oil.

You will often get foaming when bleeding the air from a hydraulic system
(you're mixing air and oil under pressure after all). Simply let it
settle out for a day or two and recheck and re-top it off until you're
running clean.

Why motor oil? Usually they use ATF or real tilt/trim fluid. Motor oil
is a lubricant, you need hydraulic oil. Usually different stuff

My Mercedes Unimog industrial tractor uses SAE 30 engine oil in the
tractor hydraulics. The backhoe has a separate pump and reservoir and
uses Case hydraulic oil.
