I have a 1996 2.5 Turbo diesel Ducato motorcaravan with 145,000 on the clock, until lately the garages and myself used Fiat 15W 40 mineral oil as per the Handbook. At the last service they put in Pure...

I personally do not believe in going down in viscosity especially with a diesel as the bearing loads are high and heavy oil keeps the running items apart
there is no advantage in using a synthetic oil because of the high compression pressures ( up to 500psi) there is increased fire getting to the oil in the sump
add to the fact that it is a turbo the oil is used to cool the underside of the piston and causes extra oxidation and carbon in the oil
regardless of the oil base , all of the additives in the oil are neutralized quickly and the oil has to be changed on a regular basis so expensive synthetic oil is not cost effective
Stick with what you know and depending on the ambient temp that you are operating in even go up to 20w-40 multi-grade oil

How to clean intake on 2001 vw beetle diesel

Hi Jay, What do you need to clean and why? If the intake is fouled with oil it would seem to me that the turbo has become defective and is leaking oil into the manifold. Let us know what the problem is and if you want to clean the outside or the inside of the ducting and manifold? there is a great big difference. Regards John

What type of oil do i use in a t reg ford focus

what is with brits and T or 55 plate ,this means nothing to me but some sort of secret code .anyway enough of my griping and question--- oil ,now best advice i can give here is to buy the cheapest oil you can ,either mineral or synthetic its ilrevelent then change oil every 6000miles and a oil filter every third oil change this will keep the engine clean inside ,you can use a diesel turbo oil as well which is better in fact as its a detergent oil ,never mind the pundits with their buy this oil at a silly price and only change it every million miles .This sort of thing causes clagging of built up carbon within the engine which kills it eventually ,Shell rotella 30 was what was put in the ford engin
es in the 70s when i worked in the quality control lab in dagenham and it was put in all the engines from the 997cc escort too the dorset line big turbo diesels that went into the ford "D" series .Does T plate mean 1978 ??? only made cortinas then real essex boys car was that and a 2 litre petrol transit .you could outrun most police cars with one of them in their time .

What kind of oil is best for my bug. It has 114 thousand miles on it

For VW gasoline or diesel engines it is recommended to use 5w-30 SYNTHETIC, but needs to meet the VW standard 50200-50500 (most if not all Mobile 1 oils do).

What type of motor oil should I use for a 2001 jetta tdi?

There's a few that you can use - but in general

Use Full Synthetic only for the TDIs...

There's various schools of thought after that in terms of 5x 30, 5w 40, even 0w 30 or 0w40

I've been using Castrol Synthetic 5w 30. The original specs for my 2000 Jetta TDI may have been for 5w40 oil formulated for diesels - but with the Synthetics now I think the 5w30 is felt to be the best in terms of what works best in the Turbo

You can probably go every 5,000 to 7,500 miles between changes - a good thing since the synthetic oils are more expensive

by the way, some also suggest changing the fuel filter at every oil change. I'm thinking that's a bit much but others may disagree... maybe ever 15,000 miles for me

My wife has a 2000 diesel beetle. This last month

Well, a little oil in the intercooler is okay but a lot is not. Excessive oil in the intercooler usually means the seals in the turbo are leaking. VW diesel have a very bad problem with clogging the intake with carbon. If you remove the intake tube at the throttle body, hold open the "shut down" plate (the butterfly in the TB) and look with a light you will most likely see a huge restriction from goopy, black, carbon. The only way to clean it out well is to remove the intake and clean with carb cleaner, wire brushes and chisels. This could be the cause of overfull oil level (unburned fuel leaking down the cylinders due to lack of air flow from intake. I have seen and repaired lots of these and this sounds like your problem. Best of Luck

My 2002 Bettle TDI has very black oil after 5000 km Why?

City driving is about the hardest thing you can do to engine oil. If your primary driving is city driving it would be advisible to cut the oil change duration by a third to help keep it clean.

How often do I need to change the synthetic oil in a 2003 jetta tdi? and what grade of oil is best?

Change it every 10k miles. You have to use 5W40 FULL SYNTHETIC oil. Not just any oil! You can buy Shell Rotella T 5w40 or Mobil1 5w40 Turbo Diesel Truck oil at Walmart. Both of these oils meet VW's TDI oil requirements.

2006 VW NB convertible 5 sp manual oil requirements

What engine do you have? If you have the 1.8 turbo engine, you absolutely need to run synthetic - the 1.8T engine is known for oil sludge issues, and running synthetic will stem that a bit. You'll still have sludge issues, but they can be held at bay. Use synthetic oil only, and do a treatment with SeaFoam (available at parts stores) every third oil change, and you should be fine.

Now, just because you need synthetic oil, does not mean you need to pay $13/qt for it from a dealer. Mobil1 synthetic is excellent oil (I used it for years in my 500+hp twin turbo 300ZX), and it's on the official Audi list of approved oils (Audi and VW are part of the same conglomerate). It runs less than $5/qt. Get Mobil1, and your oil filter, at the parts store, and change your oil at home - it'll take you 20 minutes or so and save you a bundle.
