it doesn't meet what spec?it is an acea 9 oil!also don't compare big rig diesel oil duration with car(common mistake,diesel lubricate the engine and oil lubricate it ,its like a dual lubrication system ,so oil doesn't work very hard compared to a car!rpm on diesel are very low (1200 to 1800rpm)so this also lower oil hard work.average on car is probably around 3300 rpm ,so just there alone you double the work the oil as to do also the gas is very dry so not lubricity from fuel this add more work the oil has to do so we can safly divide by 2 again .so on dino oil say 25000 mile for big rig will end up about 6500 mile for care on dino oil,and I I also forget to mention that on big truck filter never let particulate in 20 micron might be common on gas but big truck it is more like 1 to 4 micron for same efficiency .this also also permit longer interval between oil change.so no I would stay with the 3500 to 4800 mile oil change whatever advertiser say ,go on youtube or online ,ask big rig engine maker their view .they wont sugar coat it ,they cant !why?because this stuff as been often in the pass problem that could have been prevented if they had not ignored it !if a big truck engine make like say mack or Mercedes tell you they need x feature in x item ,don't sweat it ,it was tested.some think this will make engine last too long ?bof ,not really ,it just prevent issue from coming up during the life of the truck.nobody on the trucking maker side want to be seen in a bad light!because if the truck behave now ?then it make for an easier sale in 3 or 4 year.and less issue when they take back the old truck to resell
