Traveller 15w40 Diesel oil has had a decent reputation over the years and was made by Warren Distrubution however now it apparently is made by Martin Lubricants. Does any of you have any info on it. I know it’s on Fordsapproved list I’m just curious about the additive package in this CJ-4 / SN oil now made by a different company. Does Martin have a better reputation than Warren? I’m just trying to figure out if the new Traveller 15w40 is better quality than previous, same or better. Any info would be appreciated. Also.... I know Fords new Diesel oil requirement is not met by all companies CK4. But is the requirement a Min of 1,000 PPM of Phosphorus? I, asking because that is what Motorcraft advertises on their bottles now. I’m assuming that means all oils on Fords approved list are a min of 1000 ppm? Is this correct.
