Subaru Oil Level
« on: August 10, 2017, 02:14:53 PM »
These pictures should clarify the oil level for everyone who screws the dipstick in to check. The video shows how to check without screwing the dipstick in. You choose which one makes you feel warm and fuzzy.  \./8

Now I'm confused. The Subaru owner's manual shows the maximum and minimum levels to be at the hash marks at the top and bottom of the stick. Their diagram indicates that the bottom of the threads is the minimum and the max is right at the opening.

Subaru doesn't test their engines in a boat at an angle. Filling the motor to the "full" mark and you will end up with full throttle spitting, sputtering, smoking and sometimes even idle issues.  The level I showed is what's worked best in all the engines I've run in real world testing. The problems don't show up immediately, you could run a few miles before power drops off and strange things happen. The mark I made should be considered the "full" mark.

The dip stick you've shown appears to be void of threads.  This would imply that the measurement would normally be made with the dip stick screwed in against the gasket. Is this correct?

Personally, I use the eyeball method; keeping the level at the neck just beyond the threads in the crankcase and checking it often.

I think you just explained the performance problems I had after my first oil change! Thanks!!  :)

The gasket seated is how you are supposed to check the oil with the dip stick, I cut the threads off to make it easier for fast checking when I don't want to pull the motor out. On the bench I use the eyeball method too.  \./8

One last point... You say the engine sits at an angle when in the boat. Do you mean when you're underway on plane?

I am wondering if there are inconsistencies between various motor mounts which might result in a different visual oil level depending on the model year. While resting on a level surface, my ES-Kape Subi engine is elevated in the front by the motor mount. Are all motor mounts for Subaru engines the same? Will they all rest at the same angle on a flat surface or will ES-Kape mounts rest the engine at a different angle than an original Mokai hull's motor mount? Forgive me if I am over complicating things. This is an area where I don't want to make any errors  :)

The ES-kape will sit at much more of an angle on the bench than the previous models, but that doesn't change the oil level requirement as the oil level should be checked with the engine level. So on the ES-kape, you would prop the back up when checking.

Tom, thank you for the prompt response (saved me from running too low tomorrow).  \./8

Not to make a simple task more complex then it is but just to make sure I've been doing this right. Because the subaru sits on an angle on a bench leveling it with a 1/2" piece of plywood on the drain side seems to be about right, but even a slight difference makes quite a difference on checking oil level. Any suggestions on proper leveling of the motor?

I just visually make sure the motor base is parallel with the bench it's sitting on.

Do you prop it up? In other words, if the bench is level does the motor sit level in relation to the dip sticks more or less?
