How do you change diff oil?

Jim

That's the go, the diff should be full up to the level of the top bung. You'll need one of those oil syringe gizmos ... or a length of plastic tube on a funnel, if you can stand there all day waiting for the oil to find it's way through.

Hi Jimmy, i use penrite LSD oil as advised by a diff specialist. I also found it cheaper and easier to get the diff man to do it as the oil is very exy. It cost me about $120 to do both diffs and gearbox and transfer all with penrite, i was also told to change the LSD oil every 20000 ks as it is a self depleting oil. Col

I also use Penrite LSD oil, but get a lot more than 20k out of it without problems.
I do the front diff far less often as it does a lot less work than the rear, and is not LSD.

Irrespective of what oil you use I found that the simplest way to do it was with one of these pumps that goes in a drill... with plastic hose either end... job done in about 3 minutes.

i bought from a car accessory place a (tom thumb all purpose utility pump) it is a 1 litre plastic bottle with a pump that you push down on the top and on the end of the clear plastic hose there is a s shaped aluminium pipe that you hook into the fill hole . cost me about $20 . or alternatively my father just put some clear plastic hose into the top of a soft drink bottle cap , siliconed it in place and he just squeezes the soft drink bottle to get it in . (you have to think of ways to do things without spending money when you are a pensioner) .

As others have said Pentrite..

U went to Mobil servo bought one of their 500ml bottle of diff oil with the hose on the nozzle, and MT'ed the oil out of it first, filled bottle with Penrite, and used that, took 10 mins, the stuff is like Molassis...

Just a quick tip that will save you a lot of trouble and cursing, make sure you can undo the filler before you undo the drain plug, simple but done the other way can turn into a nightmare!

Jimmy,
For the best oil for your patrol go to www.bimlube.com.au
As for how to get the oil in , find yourself a sink pump from a caravan. It works real good.

Thanks foe all the advise guys.. Looks like penrites the go and all I have to do is decide which method to use to get the stuff in there.

Good advise to take the top bung out first. That had crossed my mind as there is always one.....

Interesting how word of mouth leads people to a certain brand of boutique brands of lubricants. Penrite is a very small oil company with very limited resourses, probably producing a reasonable product and with some good PR. But like boutique beer; is it really any better than the large esstablished who pour billions of dollars each year into R&D.

I'd bet that Penrite spends miniscule amounts on product development and research compared with the large oil companies. Unless they have an in, or are secretly owned by one of the larger companies I don't know how their products can possibly equate to those those produced by the larger global oil companies.

I don't use Penrite because I know they cannot produce a product as good as the big fellas. If they did they would be bought out. Im not saying there is anything wrong with Penrite it but I choose products produced by a very large fuel and lubricant companies that spend billions each year on research and development. Their products are used extensively in aviation, farming, and heavy industry around the world. They can't afford to be wrong or get a bad reputation.

I won't say which one to use because you can make your own choices amongst several. Don't get suckered into boutique brands simply because they are a boutique brand. Thats a marketing ploy in itself. It doesn't make their product any better. They can't really complete with the big fellas. Penrite is not exactly that cheap either and that still doesn't make it any better.

You should go to somewhere like Super Cheap and get one of the pumps that can screw onto the oil container. They make it quite easy. May have to extend the length of the hose as it's bloody difficult whilst lying under the vehicle.
