For those that do not have any older flat tappet engines... It really is of no consequence if you believe modern oils are ok in older engines... For those that do have those engines, if you don't believe it by now you eventually will believe it.. our last 2 cam failures were mopar
Dodge cams, the rest of the engine looked great... the cam lobes shot. These were not extreme radical after market cams... AND the engines regular oil change with Mobil1 synthetic.
After discovering the EP reduction in engine oils has been linked to a lot of cam failures, I started using a ZDP additive with Mobil1 oil and have recently switched to Rotella T6...
in theory there is a problem, AND in reality it does make a big diferance...
The place in diesel engines that also needs a bit of ZDP help is the injector rack cam...
Not saying anyone else needs to add anything to their engine oils... but I do, and I change my oil annually, gas and diesel ... old and modern.
Back to the OP there are a few reasons to run diesel rated oil in a diesel engine. Low or no ZDP pack is only one of them. KennyV
