I've allways used 10w40 in my v40's, petrol and diesel. Currently using Shell Helix 10w40 which you can get for less than £20 for 5 litres. Eurocar parts stock it as well as many local motor factors. If ordering from Eurocarparts search on google as they allways seem to have 25% off offers on service parts.

The results from averaged out oil analysis studies show very little difference between the major brand oils and the full synthetic school folks only do slightly better in engine life terms. Which grade of oil you use is more important as a 0W oil is better in winter if the temperature goes below minus 25C, otherwise a 5W is fine in winter. Once you move up into the 10W group, there is a slight increase in cold start wear. 5/30 oil is OK for an engine in good condition that has a low oil consumption and no leaks, but the Volvo dealers and various good oil finder sites will recommend 5/40, partly because the oil consumption will be lower and there is no cause for concern if the oil shears down to a 30 grade by the end of the OCI. Both the go cheap school and the go long school recommend using a real Volvo filter, although if one is not available the Mann or Bosch ones are also fairly good. The big engine oil killer for old cars is coolant or fuel contamination, as the anti freeze kills the oil additives and the fuel seriously reduces the oils lubricating property, mostly by dilution. So if your engine is smokey or the head gasket is bad, change the oil frequently if you can't fix the problem. Never forget a cars useage will directly effect the engine oil, so too much time in traffic or doing short stop starts is bad news, as is a big right boot with a cold engine and if you want to avoid a case of black death (Sludge), don't use ultra cheap supermarket or Internet special oils because they might not have enough detergent or anti wear additives and when you combine their use with a longish OCI or too much time stuck in traffic, they are bad news in the long term. If you have a diesel V40, there is a very minor case for using a diesel only oil (B4), as the major brand diesel only oils contain higher levels of detergent additives and help to clean any traces of old sludge out. The two that seem good are Liqui Moly Diesel Synthoil 5/40 and Mobil Turbo Diesel 0/40, but any major brand diesel 5/40 will clean out old traces of sludge. For those of you who are in a more technical reading mood the following is a copy of my second UOA (Used oil analysis): Basic block: Renault 1.9TD 130hp but detuned by Volvo turbo settings to 115hp for old V40 phase 2 diesels. Oil: Liqui Moly 5/40 High Tech Synthoil & Volvo filters. Total KM: 190,000 OCI 10,500km Top up 0.3 ltrs. Useage: Not much autobahn, no traffic jams, but lots of stop starts and driver abuse. Lab: Blackstones Comments: Good. 10,5K km(Last oil change)/9.5K km (Previous OC) / Univeral average for 8K km OCI and F9Q2 block (Figures from Blackstones Laguna 1.9D data) Al 4 / 5 / 7 Cr 1 / 1 / 4 Fe 33/ 24/ 45 Cu 6 / 5 / 5 Pb 3 / 2 / 5 Moly 3 / 3 / 28 K 3 / 5 / 1 Boron 63/ 62/ 82 Si 14/ 11/ 14 Na 3 / 5 / 54 Mg 5 / 8 / 228 Ca 3107/ 2751/ 2481 P 1039/ 942 / 1081 Zn 1245/ 1049/ 1212 Sus: 66.3 Should be: 66-78 Previous: 67.9 (Mid 40 down to almost the top of a 30 grade) Flashpoint (F): 440 Should be: >410 Previous: 425 No fuel, Antifreeze or water detected, Insolubles: 0.5 /Previous 0.4 (Limit 0.8) TBN Not measured at last UOA, but was 4.7 with previous (VOA 9.6) My summary: The oil is still in good condition and would last until 15K km, the bearings, top end and rings are in excellent condition, although there was a very minor increase in Iron content which is a general wear metal and might be corrosion related, but the figure is still good. One very odd discovery was that Liqui Moly have changed the base stock and additives pack for the better, as all of the main detergent and anti wear additives included in the oil increased and the flash point was higher. This was confirmed by the Blackstones analyst. The reason the figures are good is that the engine was run in when new correctly and the previous owner lived in a town with no traffic jams and spent most of his time on the autobahn. He used cheap Mobil 10/40, but although that is not an ideal oil choice it is still a fairly good oil. Last edited by skyship007; Dec 16th, 2012 at 14:01. |

The BMW forum chaps averaged out all their used oil analysis results for an average 5K mile OCI and the big surprise was that GTX 5/30 (Part synthetic) beat Mobil 1 0/40. Castrol Edge 5/30 did only slightly better than the GTX, but in reality there was not much difference between the different oils used. It is more important to figure out a good change interval than fuss over which major brand oil to use, but the importance of top quality air and oil filters should not be overlooked. I am hoping that Mobil 1 is going to start selling EP long life oil filters in the EU soon, as that will help reduce the number of oil filter changes required, as there is nothing wrong with doing oil only changes in between main services. I do 10K km oil changes with 20K km oil filter changes, as dirty filters work better than clean ones. |

Same. I think it's decent stuff. I change it every 6k miles.

Shell 10W/40. Volvo Dealers provide this too now for S40/V40.
