Servicing / 5w40 Oil

JustinR1979

Think he meant normal driving as opposed to redlining it everywhere and racing about
For short trips I'd worry about changing it more often than the quality.


Really, oil has come on a long way in recent years, most of it is better than anything you'd have gotten in the past.

Spot on Justin1979, probably better to change with a cheaper oil more often, than with an expensive oil less often

If the OP's TDI uses the PD type fuel system then i'd make sure that any oil they do decide to put in matches the manufacturers specs or exceeds them.
For the PD engines, putting the wrong type of oil in (even if the viscosity is the same) can cause the camshaft to wear out rapidly which then causes misfires and poor running.
For these engines you really need "long life" oil but still service them regulary.

Is this 5w-40 a Volkswagen recommended viscosity.

I thought these engines needed a 5w-30 oil.

Have you checked on an oil-finder site?

How old is this car?

Oil recommendations change as oil technology improves - I wouldn't just be continuing using what VW recommended 10 or more years ago.

All oils are from mineral oil (hydro carbons), including synthetic, synthetics are just ois=ls that have been refined more and have more of the useful constituents because they have been filtered more.

5w30 long life oil, 5w40 regular interval.

I just did an oil change and used the recommended Castrol Edge 0-30 fully synthetic stuff. My car only takes just under 4 litres for an oil and filter change. According to the fuel computer, petrol consumption has gone up. I dont trust garages and prefer to buy my own oil and do it myself.

The oil cost me £32 for 4 litres.

Curiously i was in a BP garage the other day and whilst waiting to pay, i browsed the motoring spares shelf and saw that incredibly, they had 1 litre packs of the same oil on sale for £25 !!!!!!

Obviously relying on desperate/impulse buyers..tidy profit there.

I think that if you do nothing else to your car, at least put good oil and a filter in it once a year.

No, they're not. They can also be made from scratch using raw materials other than modified base stocks. These are synthesized to produce a base stock lubricant and are categorised as PAO-based (Poly-alpha-olefin) synthetics.


One of my customers makes this stuff.

Hang on, you don't trust the garage, but you're happy your petrol consumption has gone up? That suggests to me something is wrong.

I used opie oils yesterday.
I was going to the checkout when it asked me to log in, so I did as usual.
Then a box popped up asking me why I was leaving the order (which I wasnt I was just being redirected for login) and gave me 15% off for leaving a comment. all I left was "I was just logging in"

not bad considering it was cheapest anyway and then a extra 15% off

As I was buying Plugs/Oil and Genuine Subaru oil filter was a nice little saving

the code was SAVE15
