Re: Mobil1

you would want mobile delvac 1, that is the synthetic.

the older mobile 1 was rated for diesels but, when they changed the rating standards cj-4, the mobile 1 you can buy now is not rated for diesel engines that require cj-4.

delvac 1 is good fluid.

The mobile one I just bought is rated for cj-4 and ci4.
I think all the new mobile 1 that there coming out with has the cj-4 rating now. Beleive I read that on mobile 1 web site.Some of the old may not be cj-4 or ci-1 whichever it is they said to check it out on the shelves before buying.

Re: Mobil1

Mobile has put on the general market, Mobile 1, Turbo Diesel Truck. I think it is the public version of Delvac 1. I have always used Delvac 1 up until this came out and then switched on recommendation of the local dealer.

The rating on the back is: Meets the API CI-4 Plus/ CI-4/CH-4/CG-4/CF-4/CF and ACEA E5/E4//E3 industry standards.

I have been buying this a China Mart for about $24.00 and run it usually to 20,000 miles with filter changes and oil samples at 5, 10, and 15 thousand miles. I change the oil at 20,000 unless I get a bad oil sample, which I have never had. TBN numbers on the Powerstroke after 10,000 miles the last time was still at 10.6 and 6.6 in the Jetta ( I bought it used with no history of maintenance and the oil looked like black glue). The Powerstroke has always had a 2.5 micron filter on it and the Jetta was a first time change and oil sample.

Both engines now have 2.5 micron filters and you can still read all of the info on the dipstick at 10,000 miles. Both engines have a oil additive called TX 7, which is a polymer based oil additive.

Re: Mobil1

Have any of those oil analysis reports? I would be curios to see the viscosity & oxidation levels on Mobil 1 after 15K miles.

Re: Mobil1

I changed the oil and it sounds a like it is not as loud when it is cold.
