44GPW Posted May 6, 2014 Share Posted May 6, 2014 Hi guys, Just doing me pre France vehicle maintenance. Can someone please advise of the engine oil weight for an MW. Thought i'd seen it on here somewhere but cannot find it. I use the Halfords Classic 20w50 (Green/Cream tin) in the Jeep. Would the same be ok in the Bedford or not?? Thanks Richard Quote Link to comment Share on other sites More sharing options...
0 Tony B Posted May 6, 2014 Share Posted May 6, 2014 I use the same in both my Dodges, lovley stuff! Worth flushing the MW engine before using the 20/50 . Get rid of the muck before adding a detrgent oil. The flush I use is Forte, not cheap but does the job really well. I flushed out my WC54 with the stuff and then put her over to Halford's 20/50. After a couple of hundred miles the oil is still spotless clean. Quote Link to comment Share on other sites More sharing options...
0 No Signals Posted May 6, 2014 Share Posted May 6, 2014 Although I agree with the principal of flushing an engine out, I'd be hesitant to flush an engine that is running fine so close to a major event. It is not impossible that removing a few decades of crud will open up a few leaks that otherwise had been holding well. In an extreme case, thinking about one I know of, even cause a drop in oil pressure due to opened up 'tolerances'. Straight SAE30, low detergent such as the stuff Morris Lubricants supply is what you need. Quote Link to comment Share on other sites More sharing options...
0 Richard Farrant Posted May 6, 2014 Share Posted May 6, 2014 Straight SAE30, low detergent such as the stuff Morris Lubricants supply is what you need. No Signals ......... you are quite correct. If an engine is unknown and has been running on a straight low or non detergent oil, then using a multigrade detergent oil is going to loosen the crud. We have gone though this many times before. These engines do not have full flow filtration and therefore that is why we still use straight low or non detergent oils. Ask the oil companies tech departments, they will say the same. regards, Richard Quote Link to comment Share on other sites More sharing options...
0 rampant rivet Posted May 6, 2014 Share Posted May 6, 2014 I use straight oils as per original spec have run the jeep on SAE 30 for over 20 years no probs so far :shocked: think MW is SAE 30 too. Quote Link to comment Share on other sites More sharing options...

I don't understand some peoples obsession with 20/50:nut:,it must have something to do with the ad campaigns conducted years ago by Duckhams and Castrol:D Quote Link to comment Share on other sites More sharing options...
0 Tony B Posted May 7, 2014 Share Posted May 7, 2014 I do remember the Q20/50 motor oil TV ads as it happens. :-D My experience has been the 20/50 keeps better presure, especially after long runs in hot weather and the pressure loss recovers quicker when idiling.
