Traveling in NV mts, I lost oil press at 4100rpm. Immediately returned to normal when I let up on gas.After 3rd time I figured there was trouble. Search on this forum & found someone with exact same problem. They said it was A too restrictive Fram filter. Recommended a NAPA 1060. Immediately bought & installed one. Press went from +-30 to +-40-normal driving. Filter has an internal by-pass for cold starts & hard pulls. +-50 cold. Have passed 4100rpm a number of times in 2mths since installing filter. No problems.This is a full quart filter. MANY THANKS TO WHOEVER POSTED THIS FIX. It removed a lot of stress driving in the western mts.

Philbert, I copied your post over to the Workhorse Chassis forum, where more Workhorse owners might see it.

Philbert, thanks for the information, I have just ordered a Pace Arrow with that combination. Are you happy with the 8.1, how does it perform in the moutains?

Note to Max49: This why we don't use FRAM filters.

I think the Fram also has a bypass. I think all filters have a bypass. If they didn't there would be a lot of blown engines.

Fram had problems ~20 years ago and never overcame the bad press. The same thing happened to Pennzoil.

I like and use WIX, NAPA or AC filters in my W24.

Thanks for the thanks.

philbert... do a search on the Workhorse Chassis forum about loss of oil pressure at high rpm (or something to that extent).

Apparently there is, or was, a posting from Workhorse regarding oil pressure dropping to zero at 4500 rpm or so. Can't remember exactly but it's apparently something in the programming and is not a failure problem.

I'm surprised "Driver" didn't mention this. He's usually right on top of these types of issues.

I know you mentioned 4100 rpm but maybe something isn't exactly correct in your rpm or the ECM programming.

I do know about the anomaly with the FRAM and the fact that philbert hasn't been able to recreate the event since he's switched filters leads me to believe that he has found a working solution to the problem.

In other words I think I had a CRS moment.

I'm not faithful to Fram, but I've been using them on and off since about 1970 and I've never had a problem. Now you guys are trying to scare me. The only problem I've ever had with an oil filter is a Baldwin, made by Wix, and that is they are bad for leaving the old rubber gasket sticking to the engine, and if you don't notic that, you're going to have a mess when you start your engine.
I don't remember what oil filter I now have on the MH but I sometimes wrap it out to 5000 RPM climbing these mtns. If my oil pressure dropped tom zero , I would have been walking home.

My son, just today brought home 6 qts of oil and A Fram filter for his Explorer. I saw the Fram and thought of Driver instantly.
What's wrong with Fram? Do we also not like Prestone, Autolite and Bendix?

No oil filter cartridge that I know of is invulnerable from leaving the gasket on the base of the oil filter mount.

You have to make sure to check it. All manufacturers suggest you clean the mating surface and in so doing you will see if the gasket is stuck up there.

I know that now . But that was the 1st and only time , it happened to me.

school man · 07-12-2007, 07:32 AM

Sounds like a gauge or wiring problem, No oil pressure at 4100 rpm under heavy load and you would be walking. My son's 2003 has eaten up three pressure gauges ,reads zero pressure but yhey change gauge and starts working again.Good Luck Mike 8.1L

It is a known fault with the oil pickup tube and the combination of the Fram filter. By changing back to a GM filter - the problem was eliminated.
It is NOT a GUAGE or WIRING problem. If ignored it could dammage your engine.
Now I use a scan guage from http://www.aeroforcetech.com/ and it saved my but when my oil pump shaft sheared 2 months ago.
It also allows me to monitor my coolant and transmission temps.
I was lucky and stopped the engine when the warning came on and the guage showed 0 psi. All I had to replace was my hair (now bald) and the shaft. All the bearings were ok.
