No one has ever told me the the difference and if a diesel oil can be used in a petrol car....

 

where's 'bal wheen you need him

 

Diesel oil has detergents in it to combat corrosion that is caused by sulphur in the combusted diesel,

 

can u use diesel oil in petrol engines?? if so, does it offer any advantages over petrol oils?

 

No - it will bring you a 3 grand re-build bill if you try it

 

lol. ta. always wondered. howcome u can use petrol oil in diesel engines then and not t'other way??

 

Just twigged your on about lubricant not fuel

Diesel 'oil' to me is the stuff you get out of the pump

 

rofl!!

Now ive tried optimax, super unleaded and octane booster to up performance, but i somehow dont think diesel would do feck all to make me go faster

 

diesel engine oil is VERY similar to petrol engine oil

some products are EXACTLY the same formula!

Alex

 

i thought that, but would like to find out, seein as i sell the stuff

 

Here you go:

"Can you use gasoline engine oil in a diesel car and vice-versa?

Because gasoline engines and diesel engines run on different fuel, they have different characteristics and therefore the performance requirements of engine oils must also vary accordingly. Dispersion cleaning properties (washing out residual particles such as sludge to keep the engine interior clean) and anti-wear protection for the camshaft are especially important in gasoline engine oil. Furthermore, gasoline engines are equipped with catalysers to purify exhaust fumes and an oil formulation that prevents adverse effects to these is essential. Diesel engines, on the other hand, produce more soot and so an ability to control the soot build-up is crucial. Also important are antacid properties to neutralise the acidic particles that are produced by the combustion of sulphur present in diesel fuel. As particular emissions are more controlled vehicle manufacturers are designing engines with emissions equipment that requires high performance oil. Consequently, it is not advisable to use gasoline engine oil in a diesel engine, or diesel engine oil in a gasoline engine. The SL, SJ, etc. performance ratings of gasoline engine oil all begin with the letter 'S' (Spark ignition), and the CF, CD, and so on of diesel engine oils with 'C' (Compression ignition), so it is quite easy to tell them apart. [Gasoline/Diesel dual use] engine oils that carry the rating [SJ/CF] have been specifically formulated for both types of engines and can be used in either, according to conditions of use. "

Straight from the Castrol website:

Gasoline is what we Yanks call 'Petrol' for you council-estate types!

 

thanx for that....always wondered what the sj/cf ratings were about.

that answered 2 questions in one

 

And more modern engines are more fussy on the type of oils used!! I have read somewhere that the PD Engine in my VW will hardly run if the wrong oil is used

 

Yup. PDs run differnet oil.

But Variable Diesels and Petrols can run the same Oil just to confuse things.

 

the VAG engines are only supposed to use castrol SLX longlife or else it also voids any warranty.........remember that when u see the price of 1lt for a top up...........Ł15 quid!!!!

 

Yeah DAve tell me about it i bought a 1ltr top up as i always like to have some in the garage. And cost me 10.50 lol

 

You do know that accepted tolerance is 1 litre every thousand miles don't you
