Hi, I have had two BMW 3.0 diesels over the last 12 years and I have managed to put great mileages on them with regular maintenance. The oil spec was always 5/30 LL04 but a while back BMW changed to the 0/30 on the later models to try and help fuel consumption. I have just bought a 2019 X5 30d...

Just wondered if anyone has found a high oxidation result on Delvac 1 5/40?, the first analysis was done at only 200 miles and then at 1800 and both results were high.

Thanks for your reply, glad you think my pressure is ok, I remember years ago with classic cars people liked to run 2-3 bar even at idle but I guess oils and engine components have come a long way since. I did find an article on here saying 10psi per 1000rpm is a good practice. Just wanted to...

Hi, just about to fit a hybrid turbo and tubular manifold to my VW T5 2.5 PD but before hand I wanted to add some extra gauges for oil pres/temp, EGT, boost etc to make sure everything is working as it should. The only spec VW give is 2bar @ 2000rpm @ 80degs C. At 90degs C I got:- Idle- 0.7...

Originally Posted By: SilverC6 Have you changed the filter lately? With what? OEM? Castrol 10W-60 might be the prescription if the VW spec oil isn't cutting it. Fitted a new VW filter when I changed to Delvac 1 last month, the VW Quantum oils are actually made by Castrol. The only reason I...

Originally Posted By: m37charlie Actually the MB904/906 uses flat tappets on the valves and they do not seem to be a failure issue. Of course the peak hp is at only 2200 rpm and it is governed under load at 2500. Charlie I think the main issue with the PD engine is the narrowing of the in/exh...

Originally Posted By: m37charlie For what it is worth (admittedly not much): 1) are you sure the noise you hear is rattle from the cam followers? 2) analogies aren't worth much at all, but...the MB904/906 engine is a PD design and the Delvac 1 you are using has the top MB rating (228.5) for this...

Originally Posted By: fdcg27 Wow! I wonder why the one on the right looks so good? Do these things actually get hot enough in service to turn the steel blue? Looks like it. The one on the right was the best one out of 10 and the other two were the worst. I wonder if the blueing of the metal was...

Thanks for the reply's guys. I only switched to the Delvac 1 because of the good reviews and oil analysis guys were getting on there PD's compared to the VW 505.01 and 506.01 oils but from memory they were mainly 1.9's. The VW T5 2.5L PD R5 engine and Toaureg 5L PD V10 engine are renowned for...

Hi, I have recently put UK spec Mobil Delvac 1 5-40 into my VW T5 2.5PD and straight away I have noticed you get lifter rattle at first start for a few seconds now. The cam and lifters were new a couple of months back and I get no start up noise when I was using the recommended VW oil for my...

Any more recommendations guys before I buy some new oil?. I can get Mobil Delvac 5w 40 and Fuchs Pro S 5w 40 locally. 20L of Delvac is around £140 and the Fuchs is around £180. As the VW R5 2.5 engine has a gear driven camshaft its not the quietest engine to be honest, I was hoping changing...
