Re: What type of engine oil is used for a diesel
Go to any auto parts store, like an auto zone and tell them what you are driving. They have a data base which will guarantee that you get the exact oil that you need.
I use Mobil Delvac 1 ESP 5W-40 , a fully synthetic supreme performance heavy duty diesel engine oil that helps extend engine life while providing long drain capability and potential fuel economy for modern diesel engines operating in severe applications. Mobil Delvac 1 ESP utilizes state-of-the-art technology to deliver exceptional performance in modern low emission engines, including those with Exhaust Gas Recirculation (EGR) and Aftertreatment systems with Diesel Particulate Filters (DPF’s) and Diesel Oxidation Catalysts (DOC’s). Therefore we believe it will be a good oil for the high mileage vehicles with the proper care for your vehicles as recommended by your manufacturers' guidelines.
Need more info as to what engine you have. The older non-epa engines typically used 15w40. The old 2 stroke Detroits used low sulfated ash 40 wt. Most of the newer big diesels use CJ-4 15w40 while most of the Mercedes/VW's use the 5w40 turbo diesel oil.

It will be a diesel oil only, with a viscosity rating of 15w-30 or 20w-50 depending on the ambient temperature of your area. The brand is immaterial but it has to be diesel oil to have the ingredients needed to run a turbo. Oil used in a petrol engine will not be suitable for this application.
Hi John, These days most oils are formulated to be used in both petrol and diesel engines but those formulated specifically for diesels should not be mixed. If your talking of a top up I suggest a flush with a good quality chemical and a lub service. If you have had a service carried out and changed the type of oil the same applies. Mixing oils can cause fast sludge build up which can block the filter, oil pump and galleries. These days most oils are designed to run both types of engine, but mixing is neve a good idea. Regards John
yes perfectly ok ,i would use a turbo diesel oil thats suitable for diesel and petrol engines and the cheapest one at that then change oil every 6000 miles with a oil filter every third oil change ,Do not spend money on expensive boy racer market oil use what the trade uses something like shell rotella and do not be fooled by fancy adverts like liquid engineering and all that stuff these fancy long life oils cause more engine failures than any cheap oil which is changed at regular intervals to prevent a build up of internal clagg inside the engine
three squirts of washing up liquid ,has to be fairy not a cheap one ,half a litre of diesel all added to the engine oil ,run for a couple of days as normal and the noise will diminish ,Then change oil and filter but use a 10/40 detergent oil suitable for a turbo diesel ,the cheapest you can buy ,now change oil every 6000m with a oil filter every third oil change .You have a noisey hydraulic tappet nothing more which is fairly common on this engine and its caused by not changing the oil enough and using expensive long life oil which causes problems like yours by allowing the combustion residue to accumulate within the internal workings of your engine ,
I had a similar problem in my Mondeo 1.8 TD a few years ago and this was cured by changing the engine oil and filter to the correct type.
I had used the special Duckhams 10w-40w Turbo Diesel (or was it 15w-40w?) oil but once I changed it to the correct Ford 5w-30w (Formula-E ) ordinary oil, the turbo worked a treat every time.( I understand now that there is an even "thinner" option that works even better so worth checking ....Something like a 1w-30w )
A strange answer I know, but true
The only reason I used the Duckhams was because the chap in Halfords said it was the best one for a Turbo Diesel
If you have a Turbo charged engine the gaskets on the turbo are probably the culpirt. If you can lift and support the car on jack stands. Remove the lower shield from the car and inspect the turbo. You may have to remove the right frount wheel and any sheilds in the wheel well to see the turbo. The Turbo seals require relitivly high engine RPMs to seal properly. The Turbo starts to work about 1500RPM. Is it Gasoline or Diesel? The Variable vane turbos used in most USA,VW's after 1999 will start to work slightly earlier. The type of engine oil you are using, is it up to WV specifications could also be a factor. Not all synthetic oils are alike.
Upon inspection look fordark grey/black sooty deposits indicating where your leak is comming from.
the best type of oil for a diesel engine is mobil 1 , and it should be at least 10w40 if not 20w50, I'd call a dealer and ask about the weight. They can also tell you how much oil it will hold, or you can just add one quart at a time until you get it full on the dip stick, I'd say no more that 4-6 quarts total, but I do know that diesel's usually take alittle more that a standard gas engine.
