Oil recomendation

With the amount of time you guys spend with your rangies and discos off the road having the oil changed and the various and frequent breakdowns, it's a wonder you ever get to drive them anywhere except to a garage. I'm pretty sure a modern unstressed engines can go for at least 12,000 miles before it needs its oil changing.

Apologies, it is Grrr has the Jag.

Dont agree about the design. Modern synth oils are far too thin for older engines, and so slippery they can lead to glazing of the bores.
Newer engines like synthetic oils, and run more economically and have smaller oil capacities as a result of using such oils.

My Jag has the 4.0 Jaguar lump in it. Nothing as mundane as a Ford engine in there! It goes like **** off a Teflon shovel.
 
Where are the guys who use tractor universal oil nowadays?

It was fine in an old Fordson, and in fact was recommended by Ford for use in the engine, as well as the gearbox and back axle. However, I always used multigrade diesel engine oil in my Fordsons.

BTW reading your earlier posts, just thought I might mention, because your OP was in the range rover section, I had assumed the term rv8 referred to the original Rover V8 engine, a sleeved down Buick engine. In fact it seems you were referring to only the later engines. They will be more suited to synthetic oil, but pretty sure they will run fine on mineral multigrade too. Mine did.:)

Fair enough. Bloke in the marina has a Jaguar saloon with a 2.2 Duratorque. I know nothing of Jaguars. :)

Duratorque is actually a very good motor, powerful, economical, and reliable. One of the best diesels Ford ever made. :) I love my Mondeo.

For some reason, it isn't a great engine in a landrover, possibly due to the fact landrovers have manual box. :(

Ajv8 they had a few teething issues with those. Nicasil linings and supermarket fuel. Cam chains wearing. But these were sorted ( mostly by jaguar replacing complete engines by the thousands)
A modern powerful and versatile v8 though. And used in rr's
 
Hi turboman I wasn't referring to your good self with the tractor universal oil. There were a lot of people who insisted tuo was the best oil around for anything with wheels. Especially land rovers. It's an oil that can be used in everything on a tractor. Steering gearbox hydraulics etc.

Depends on the tractor. Some like TUO, some like injun oil in the engine, gear oil in the gearbox. My International liked hydraulic oil in the rear axle, everything runs off the hydraulic pump on those.

I would never consider using TUO in a landrover, or any other road vehicle. I imagine people did that because it was cheap.
 
I change my oil when it has turned black, regardless of miles or age. Sometimes I even change the filter, but not always. Col

Do that with a RV8 & you are asking for trouble, if ever I look at one with a view to buying (for myself or on behalf of a friend) the first thing I do after opening the hood is to remove the oil filler cap & shine a pencil-beam torch onto the rockers, anything darker than a brown coating (golden gets top marks) it's time to walk away :(

Yes. Petrol engine the oil should look like oil. With a diesel, a bit of blackness is acceptable, but you don't want it looking like tar.

Yes, the early ones had Nikasil liners and some owners had issues. It was the timing chain guides that were an issue and upgraded. Mine is after those issues. Apparently there was a throttle body issue for my version (2001) but people were split on whether it really was an issue or not. I've certainly never had one, other than the coil plugs going at 70k miles. Other than that it is so smooth it is inaudible unless you floor it and then it takes off like a scalded cat. Be nice to shoe-horn one into the Rangie one day.
 
My sprayer has a supercharged l322 that has the ajv8. That is bloody quick. And reliable to boot.13 mpg to.

Why would a synthetic oil be thinner than a mineral oil? At the same viscosity number they are - unsurprisingly - the same thickness....

Bore glazing shouldn't be an issue once run in, and that can be an issue with modern synthetics and "traditional" bore honing techniques but that's not a reason not to run synthetics once the engine is run in.

No reason, but they often are, modern engines are designed for thin oil, saves on fuel.

I only know what I have seen, and what I have seen is bores on old engines glazed after using synthetic oils. They are excellent lubricants.
