Oil recommendations for a 940T

Starting to get into this whole service-your-own-Volvo thing. Have bought an oil filter from German&Swedish and now need some recommendations as to what grade of oil would be best.

I am running a 1992 940T estate that currently has 145k miles on the clock. I know nothing about grades and whether an oil is synthetic or not, so all advice gratefully received.

Any tips about the job itself would also be welcome, though I'm assuming that unscrewing the current filter and draining out the old oil from wherever the plug is under the engine will be straight forward enough.

Thanks - Tim

Not being an expert, I have been deciding on oils as follows:

When buying oil, there are specifications on the bottles, barrels etc. There are several institutions with standards. I have always looked at the API (American Petroleum Institute) specifications. You can read on the packages API Sx/Cx where x stands for another letter starting with A up to ? Sx is for gasoline engines, Cx is for diesel engines. The higher the second letter, the better the oil. I do not know what are the highest specs at the moment, but in my case I buy a diesel engine lubricant with spec API CI-4

gives a short intro to the specsYou might find more info about lubricants on the website. Viscosity is another point to look at when buying, for my 745 turbodiesel Volvo I use a 5-40 synthetic API CI-4 oil in central Europe with a temp range from about +30 down to -20 celsius. This should be thin enough to secure turbo lubrication early at low temps and thick enough during motorway driving in the summer probably in most areas of the world except arctic and desert areas with temp extremes. You can find a table of viscosity classes and temp ranges at

any responsibility for consequences:Another point which I have been doing is using diesel engine lubricants for gasoline engines in the past. Usually the oils have the API Sx specification also on their labels, eg API SJ/CF, so if SJ is good enough for your gasoline engine, the diesel engine lubricant fulfilling the specs will do also. Lately my impression is that producers of diesel lubricants leave away the Sx spec on the products so the people with a gasoline engine won´t find out that the oil fits perfectly for their engine, too. The reason I suspect is that usually the diesel lubricants are cheaper than the gasoline engine lubricants. There are also other spec systems for engine lubricants: ACEA, MAN, etc but I think one still can do well by sticking to the API specs.

The booklet coming with your car should indicate which API specs the engine needs.

Synthetic its cooler cleaner and your engine doesn't gum up as well your turbo wont burn the oil left around the bearings when the engine heat soaks .I am using Mobil one or Bp synthetic in our cars because I believe its cheaper in the long run with less engine risk .As well I drove for millions of klms or miles and the synthetic oil available is quality and insurance when you run a business you need reliability.

After finding crud so hard I used a drill to remove it in my sons used Volvo,I feel justified in using Synthetic oil in our cars .The 240 had one blocked tube on the anti blow back valve due to using dino oil.Look into an engine that uses Synthetic oil ,its clean no brown or black gunk .Besides now Volvo recommend Synthetic oil .
