Hi all..

cant seem to find out which engine oil is best to use ?

I have read that vw 505 01 is good, but is that semi synthetic ??

Also read vw 506 01 is better ?

Im not worried about price I just want the best oil to keep her running smoothly the longest..

Also What about fuel..is there any point in buying Ultimate Diesel or is it all hype ?

Thanks Folks

Jonny

Welcome to Briskoda!

The highest grade VW approved diesel engine oil is 507.00. It might be over kill for a non-DPF equipped 1.9 TDi but it is required for cars on variable (vs. fixed) servicing.

You'll regret asking the supermarket vs. branded fuel question!

Welcome.

For vehicles with option code QG1, ie variable servicing, the oil is either VW 506 01, VW 507 00.

Fixed servicing is VW 505 01. Check your service record booklet. The code is printed on the first page. If it's QG0 or QG2 then it is set to fixed servicing or can't be set to variable.

Higher numbers are better than lower numbers. If you are on variable you need VW 506 01, but if you have a diesel particulate filter you have to use VW 507 00.

To be honest, I would stick to the newest standard 507.00 which is good for longlife variable servicing and is very clean - then you're safe.

Check out one of this site sponsors http://www.opieoils.co.uk/ . They have recomendations based on your car and you can search by vw codes as well.

I would change my fuel filter more frequently than recomended (two years) rather than spend money on special diesel - but that's just me. In Ireland I have no real choice it's all diesel. However, when ever I visit the Uk and use supermarket diesel my mileage drops below 50mpg. So there might be something in it.?

Hi

Thanks for the kind welcomes and advices : - )

Im a taxi driver, and do about 800 miles per week roughly, so this would mean variable servicing ?

I dont have the service book yet as the taxi company I work for keeps it until I have paid the car out.

I was reading some other forum recently and some dude who had done alot of milage said this:-

"Hello ! ´Here´s some feedback from ( cold ) Scandinavia- I have the 1.9 TDI-engine in my Audi A6 Avant 2001 and it has 490 000 kilometers on the clock by now. I´ve never experienced any engine problems whatsoever.I deliberately chose from the very beginning not to go for the Audi - " Long Life program " with extended OCIs( I believe this does not excist in the US and Canada) but have instead chosen to change the engine oil every 20 000 kms. Have always used Shell Helix 5W-40 (VW 505 01 ) or Pentosin ( VW 505 01)and the German Castrol TXT ( VW 505 01)

The Audi mechanics always wants to fill in the "Castrol Long Life III - oil" ( VW 507 00 ) but I have insisted in the VW 505 01 since this particular engine does not have a Diesel Particle Filter( which my 2.0 TDI and 2.7 TDI has )Those are common rail engines and the 1.9 TDI-engine is - as Tornado Red says - a

" Pumpe Düse " -engine. My 1.9 TDI has done numerous trips through Europe on the German Autobahns and Italian Autostradas on absolute top speed for hours - over the Alps etc....and really runs smooth when really heated up. Be careful and run smoothly as long as the engine is cold and you will have an engine that lasts ( almost ) forever...The 1.9 TDI engine is not particularily "cultivated" when compared to the 2.0 TDI with a common rail injection. Do not idle for more than 2-3 minutes on cold wintermornings before driving away carefully. A true

" carthorse "... "

What do you folks make of this ?

about the Diesel thing, I take it, it is all marketing crap ? Up north there is BP Ultimate which is meant to be good for your engine bla bla bla...

Hi

If you don't have the service book yet you can see the very same options code sticker on the boot floor under the carpet to the left of the spare wheel.

There are lots of opinions here about variable/fixed servicing but it is often forgoten that VAG/Skoda have very specific rules and advice about the two. Visit their website and if you fit the criteria for variable you can go from there. As an example, I tow a trailer from time to time and so VAG advises a change to fixed servicing.

If you are fit for changing the oil yourself between full services at a garage, I would do that and let the car have the benefit of the new oil. I can't see you saving money on variable since, on your mileage, it would be two full services with xtra money for the "longlife oil" each year compared with two full services plus two intermediate oil changes you could do yourself.

I've posted about this before, and will say again that I NEVER use supermarket fuel in my Octavias.

My 54 plate Octavia was run on a single tank of Tesco's own back in 2008, and whilst on this was lumpy, smoky, noisy, down on power and down on economy. It HATED it. A fill up with branded fuel after this cured the problem completely, and since then I'd far rather spend a couple of pence a litre more on the fuel for the better response. With the better economy, there's no difference in the cost per mile by running on branded fuel.

OK, so you think I imagined it? Well, SWMBO's old Leon TDI was exactly the same, as we found out when she filled up at Tesco to get her Tesco Clubcard points.

Not noticed anything with Tesco or Sainsbury's fuel but my Scout really doesn't like Asda diesel.

You can't generalise about supermarket fuel.

I work at a refinery. We have two refineries in the local area. I see the supermarket tankers in and out all day filling up. Same at the other refinery. Branded tankers from various branded filling stations are also in and out all day. We also sell fuel to Esso and Shell. I know the quality of the fuel we are putting out the gate as it's my job to test the stuff. I have no idea of the quality of the stuff the other refinery puts out as I don't test that, but it must meet the UK legislation at the very least.

So when I fill up at my local supermarket, which fuel am I buying? How the hell would I know unless I tracked the tanker that delivered it. It's a complete lottery.

Petrol is rated by octane number (RON). Regular is 95 octane and Super is 98 Octane (minimum). Occasionally we run out of regular and will ship super in it's place, so if you are lucky you are getting super for the price of regular (how's that going to affect your tank for tank comparisons?). Regular is very rarely bang on 95 octane - usually there is "giveaway" and it can easily be up near 96 octane, or above. Diesel doesn't have an octane number, but rather a cetane number, and I think the spec is 51 minimum. Again, noramlly there is a level of giveaway. The point is that no two tanks of fuel are ever going to be the same - all you can guarantee is that each fuel meets the legal minimum in terms of it's specs.

One Tesco or Asda is not going to be the same as another as they each get their fuel from a different source. Heck, even at the same supermarket I suspect the fuel will come from different sources during the course of the same month, depending on area.

Bottom line, buy what you are happy with. Personally, I buy the cheapest I can find.

But isn't there a difference in the additives (or lack of) that different supermarkets and fuel company's put into there petrol/diesel prior to sale?

There could be. I have no specific knowledge of any additives that may be added once the fuel has left the refinery.

What additives do you think are being added, and by whom?

Don't know where I got the idea from, but I thought petrol companies added octane boosters, Antioxidants, Antiknock agents and detergents etc. with each company adding there own formula of these?

Octane rating and oxidation stability are already standard tests on all petrol sold in the UK so no need for any additives to be added after manufacturing for general use. I don't know too much about knock but I would have thought that was more an engine tuning issue rather than an issue caused by the fuel that could be cured with an additive.
