Discovery 300tdi - What Engine Oil

There seems to be a school of thought for buying low cost oils for the 300tdi and changing often. As a first time (and very happy) owner of a 300tdi I'm not sure what oil to buy, normally I would use the best oil money can buy as I want the best protection possible.

I found this oil on the internet from difflock
4x4 Store

Any comments about using this oil or recommendations would be helpful, I normally do my oil changes at 4k miles and ignore 6k/10k recommendations

Also advice on gearbox, transfer box and axle oils would be helpful.

Thanks
Pete

just make sure the the oil u use meets or exceeds Land Rovers spec which can be found in the owners hand book.
Most oil companies have a search facility this is Castrols http://www.castrol.com/castrol/iframe.do?categoryId=9024084&contentId=7044829

I've used the difflock stuff, seems ok to me just a little expensive.

Thnaks for replies, i have recently renewed my oil with Castrol Magnatec Diesel 10w-40 B3 but had read somewhere that this is not the ideal oil for this vehicle. But according to castrol website it is - I'm confused

Any comments on Magnetec?

magnetec it just to expensive use a good quality(we use 15w40 semi synthetic) oil from the motor factors buy it in 20-25L drums for £40-50 to get the best price the tdi disco at work has done 200k with no probs

I've used the difflock stuff and it seems good stuff. There tools are good to, timing belt made easy !!!!

Geez Uzzzz ...... TRACTOR UNIVERSAL! Best of them all, and costs LESS !

How many times must it be said?

Oils with big names are just the same oils but four times the price, and the ONLY reason they get away with it is HYPE! People are silly enough to believe if you pay more it must be better. WRONG!!!!

Fully synthetic oil is NOT a better lubricant than a good mineral oil. They say you can leave it in twice as long. You go right ahead, because you are leaving the CRAP in there twice as long too, and it costs FOUR TIMES AS MUCH.

Use a good Tractor Universal at about £1.50 a litre, and change oil and filter every 5,000 to 8,000 miles depending how you feel and how black it looks. You are going to SAVE on oil changes compared to fancy oils AND it's better for your engine!

Remember, ever time you drain out the oil you are also REMOVING FROM THE ENGINE about 95% of the crap that was in among the oil. Good plan - get it out.

It really doesn't matter. They are all designed to handle the worst possible scenario - FARMERS! Have you ever seen the sorts of hours that tractor engines run? Incredible! Think ploughing. Think ... wow! ... that must be hard work on the engine .... You bet, and for hour after hour, days at a time, all on Tractor Universal engine oil, dragging a huge six-blade plough through the ground. Imagine what they must have for half-shafts.

There are several grades of Tractor Universal Oils.

That doesn't matter much either unless you are off to Siberia for the winter, or the Sahara desert for the summer. We don't have these extremes, so our climate falls happily withing all the grades. Take your pick.

The simple fact is this - ALL modern lubrication oils are so good, so long as you select one that is an engine oil, about the correct viscosity range and service specification, you can't go far wrong.

It is a FALLACY that "fully synthetic" oils are better for your engine. They aren't. They are simply chemically loaded so that in theory they can stay in the engine twice as long - along with all the gritty crap that would be a lot better in your waste oil can than being pumped round the insides of your engine. CHANGING THE OIL and filter REMOVES THE CRAP.

The more often you change the oil and filter, the sooner the crap is removed, and there will always be a smaller amount of it. It all sounds bad so far huh?

OVOLINE --- I used for 3 barrels, but my current barrel is Total. It's what the supplier had on the day.

As I say, it hardly matters at all, and what is good for the engine is a good grade of oil, about the right viscosity range, diesel grades into both diesel and petrol engines (oil for petrol engines is weaker stuff, don't use it) and away you go.

Really lads. don't fall for the hype. Castrol and the rest do not exist to make oils for your engines. No Sirree! They exist to MAKE PROFITS! The question is, how can they do that? The answer is by persuading YOU to part with as much money as they can screw out of you.

It isn't that easy to screw farmers. So Tractor Universal is priced realistically. Buy 25 litre drums and save lots of cash.

A good sales pitch but na, my Maserati would not like it..

Why not? Tell me any technical reason why the Maserati petrol engine would come to any harm using such an oil.

I bet you have NO IDEA what you are saying! No harm to you, but if you have a Maserati it's a low stressed gasoline engine, and will run fine on TUOils.

HYPE AND FASHION and IGNORANCE!!!! The oil sellers' dreams come true.

Check it out lads.

My SAAB 900 Turbo 16 ran it's last 100,000 miles on this oil, and the engine is superb inside. The Disco TD5 is only 50,000 so far.

Another example...

CBR1000RR 4-cyl High performance bike engine, revs to 15,000rpm...
Castrol fully synthetic - 10W40 @ £40 per 5L goes through the engine at a rate of 100ml per 200miles (no fault with engine BTW!)
Cheap Semi synthetic delivered by 45Gallon don't know how much it cost but not a lot more than TUO (bought in error by garage at old workplace so given away FOC! even better ) sits in engine until oil change at 2000miles... know what my favourite idea is

Gotta say Turbo diesel oil that meets specs is great have run it in all V8's racing and trialling much higher temp range than the expensive stuff Halfrauds sell you for "high Performance Petrol Engines"

You're right!

There is nothing a petrol engine can do to oil that comes close to the abuse delivered to lube oils by turbo diesels.

If an oil is fit for a turbo-diesel, it is MORE than fit for any petrol engine.

It might be a different business trying Halfrauds expensive "high Performance Petrol Engine Oil" in a turbo diesel. I think the engine would come to no good after a few K miles. The oil would not stand the strain.

Bearing might run, cams might break their surfaces, rings might pick up on the bores, that sort of stuff.

I used Screwfix oil for years, and similar when not available. I've not really found a farmers supplyer but Screwfix Turbo D has been grand.

Screwfix do not have an oil rerfinery.

Question: where do they buy their oils from, and what oil is it?

CharlesY

Yea I get the fact that they dont make it but I havent found a cheaper supplier for the same stuff like a farm supplies outlet

Gotcha .... so you buy top class oils at the best prices.
Seems like a good plan to me.

How many engines have seized or blown up on you?
