+3 on the apparent poor reputation of Fram filters. I've "filleted" a couple of filters with the oil filter cutting tool I've got, and there are some big differences in the kind and amount of filtering medium inside the different filters. For me, Amsoil and Wix filters are my favorites.

Let me see if I can get this straight, we can use vehicle oil filters on lawn mowers? How do you know which one will fit? Just take the old one in with you and match up the threads? What is a good brand of oil filter (in your opinion of course)?

Go to :

Lawn Mower Parts
and look up your brand engines filter, it will list the thread diameter and pitch along with the relief valve setting in psi and whether or not is is anti drain back. With this info you can match up any auto filter , and many believe the bigger, the better. I think you will find that the vast majority of small engine filters are 3/4 16 in the 8-11 psi and are anti drain back-it keeps the filter full of oil when the engine shuts down. Although I think this is important only when the filter is mounted upright and higher up on the engine, but I ain't the smartest person with regard to recip engines.

Actually you need the ADBV when the filter is mounted horizontal to keep the filter from draining back into the engine.

I need the Fram replacement for a Great Dane Chariot hydrastatic oil filter #GDA10137. I tried Fram's cross reference site, but it didn't list the Great Dane filter. Anyone know what Fram filter replaces it?

You need to get the model and serial numbers from your hydrostatic drive unit, then look for filters that are compatible.

Fram, Wix, AC Delco & other sites had no cross reference for that mower or filter. I did get some information on eBay & found Fram P11588 or Stens 120-372 are correct for my hydrostatic system.

Now I have another problem. My service manual say to use "15W-50 ALL SYNTHETIC OIL".

My neighbor's Hustler mechanic told him to use conventional oil and, "DO NOT USE SYNTHETIC OIL". He said synthetic would ruin the system.

Do you use synthetic oil in your hydrostatic drive unit?

I found this thread & post by "ddbtdd", so I guess I'll go with Mobil 1 full synthetic, as the Great Dane book says.

ddbtdd says:
"I recently changed the oil in my hydros but before I did I called Hydro-gear and asked what they recommend.
The man I spoke to said all Hydro gears ship out with MOBIL conventional oil.
It was alright to use synthetic but not necessary.
So then I called Snapper Pro. They suggested synthetic but said it was not necessary.
So what did I use? Valvoline Full Synthetic 20w50 just because I can!"

I also found:
All these filters cross reference to each other and are interchangeable.
If your machine uses one of these, you might want to save this.
