Did i just buy the wrong oil?

The guy at CarQuest said that Bravo brand 95W GL4 gear oil is okay for my T150 tranny and Dana 20 transfer case. But I am beginning to think not. Seems like 95W is too heavy.

Any thoughts?

Thanks

Rob Caldwell

Being in North Carolina it should be fine. It would be on the thick side if you lived in a colder climate.

I'm not so sure about that. I'm from Hendersonville, NC and I've lived in Denver, CO. Believe it or not, both have similar climates (with NC being much more humid). That might be a little on the thick side.

Just my 2 cents.

With the exception of the below zero temps which can go on for several days, right? My sister lives in Goldsboro NC and I'm quite positive that she's never had to plow the 4' tall snowdrifts that I had to plow this morning.

I live in Lake Lure, NC so we are neighbors!

And when was the last time you had to do that? I'm guessing 3-4 years ago. 50+ this weekend, you were wasting your time this morning!

Notice I said this morning, as in today. Prior to that, two days ago on Monday morning. You guys up north don't get nearly the snow we get on the Palmer divide. These pictures were in my driveway at 10am today. My house is 1/2 mile from the road and it took almost three hours with a 5' wide PTO powered snowblower on the back of my tractor to get from the house to the road. It's the first time this winter since it's been pretty bleak for snow, but this is a regular occurence every winter if there's any wind involved. The county doesn't plow our private road and not being in a subdivision means we fend for ourselves to get to work and school.

I'll post up pictures of my place this afternoon, but we didn't get nearly as much (6" maybe, half of which has already evaporated - it'll all be gone by Sunday). This was, however, the worst we've had it all year.

I just looked at the bottle again. It says EP90 (not 95). I wonder if it makes a difference using a EP gear oil or not. I am just nervous about using this oil. Other than knowing that I should use a GL4, I wish I knew what the correct oil is.

EP means Extreme Pressure, which is basically another way of saying GL5. It will have the sufurous additives which are corrosive to the brass synchros.

Another option is straight 50W motor oil. That may sound like a low viscosity number, but motor oil viscosity is measured differently than gear oil. I believe that a 50W motor oil is about equal to an 80W gear oil. You could go to a synthetic oil, which a GL5 would be ok since the synthetics don't have the sulfurous additives. Pennzoil Synchromesh is yet another possibility thats safe for the transmission (and tcase).
