HI i need to top up the oil in my vrs, what oil is best used for this??

Personally, i'm very protective of my Edition One Golf G60, which is a bit of a collectors car and still only has 100k miles on it in 18 years and I and a lot of other Dubbers stick with Quantum Synta which is what VW use, and i'm gathering from what has been written on here is what Skoda use as their normal stuff (makes sense as they're the same group).

Just working from my own experience, If mine was a newer car I might say you could go with either Quantum Synta Gold or Mobil1 as they're really high quality FULLY SYNTHETIC oils, but as a car ages and the seals aren't so good, the viscocity tends to be a bit too thin realistically and it leaks round them so you need something a bit thicker. Quantum Synta is SEMI-SYNTHETIC so for general use I find it's fine. Also, most of the VW specialists I've been to use it and have the trade MASSSSIVE barrel with a pump on top sitting in the corner: good enough for them...

As far as i'm aware, fully synthetic oils are thinner so they flow better and give greater heat dispersion, but don't quote me on that. Check out the link to look into those oils a bit further. Beyond that, you're on your own brother!

It isn't clear from your previous posts whether your car is a petrol or diesel vRS. Notwithstanding the advice in the previous post about specific brands of oil, it is essential that you use the correct VW specification oil for your car. If your car is on flexible service intervals, the oil specifications must be as below. (You can also use these if on fixed service intervals.)

Petrol engines - VW 503 00 or 504 00.

Diesel engines - VW 506 01 (only if no DPF) or VW 507 00.

See the thread below for a list of suitable oils:

I was only coming from a 'standard petrol car just needs a top up' kind of perspective. Never known it to be that specific about oil before, but perhaps that's new cars for you!

Having said that, the oils on the list are VERY thin: not sure i'd be totally convinced about putting them in a car with a lot of miles under the belt!

What year is your vrs?

if it's on fixed servicing 5w/40 502.00

variable servicing 5w/30 504.00

is what i would guess but double check your manual to make sure. Dont worry about it being too thin, the viscosity index dictactes that rather than the quality of synthetic oil.

Some modern engine WILL blow up if you put semi-synth in them.

Mechanic down the road serviced a guy's 306 HDI for years, used hte proper fully synthetic oil. Guy decides to save a tenner and changes his own oil with a good quality semi-synthetic. Within a week the engine was blowing blue plooms of smoke. To cut a long story short, that £10 saved ended up costing him £850 (replacement engine, new turbo, injectors and various other items).

I use Mobile 1 ESP (5w30), you can get it from all the usual places and that's what my local dealer top it up with.

Well my VRs is a petrol engine,

I went out and got Castrol EDGE 5W-30 (this is only for a top up), which i must say is not cheap stuff at £43.99 for 4L. which is a WV 504.00 grade oil designed to be used with Audi VW engines only. but i have to say i got about 4000 miles to 1.5L of oil, which i dont think was bad being as i like to use the engine to its full shell we say.

Engine has 10000ks on it.

Thanks for all your replys people

That's interesting, cos the parts guy at the place i'm getting my octy 1.8t from stocks Magnatec which he says they sometimes use on servicing cars: Magnatec is 10w40, same as quantum synta.

Thats ok on some cars, as long as it isnt..

1. A PD engine

2. A FSi engine

3. Running on variable servicing

The PD engines must have the correct oil due to the pressure inbetween the camshaft lobe and the injector pump below it. Oil of an incorrect quality will break down and not lubricate the camshaft properly leading to camshaft and injector failure. A similar situation with the FSi units and the high pressure fuel pump that is camshaft driven.

Variable servicing is fairly obvious with the oil needing to be good enough for 20k intervals. I have serviced cars with over 200k on them on variable no problems so the oil works.

:confused: Guys, does someone has the opposite experience:

2.0 Diesel PD engine (not fitted with DPF)

Recommended oils are 505.01 or 507.00

What happens if it is filled with Castrol Edge 5W-30 (507.00)

I'ts more expensive than 505.01 oils but it sould last longer and should protect the engine better in hard driving. It also should provide some fuel economy as it's thinner than 505.01 (5W-40).

The only thing I'm worried about is that 507.00 is thinner oil, so pottentially will be burned out in the turbocharger, and will need more frequent topping. Does anyone has some experience.

I'd be putting 507.00 in any VW PD TDI (except the earlier 2.5 5 cyl and 5.0 V10s which need 506.01).

AFAIK 507.00 offers significantly better protection to cams/followers etc, and also lasts better. It is also suitable for engines with or without DPFs.

"5W" is only the viscosity rating when the oil is cold, so shouldn't lead to excess leakage past seals (but I admit I have no first hand experience with high mileage engines with suspect turbo seals).
