I had seen that video, thanks for posting it here though. I love his true indignation about the low quality of the Fram.
Used to use only Fram on my cars as they had the correct hype, and that is what dear 'ol dad used! (Turns out, crap product to go with it!)
Having always used Wix for any marine diesels I have been in charge of, I gravitated to Wix for my trucks and diesel vans as well.
A good friend, and great engine guy told me to use "The best filter you can buy and, a good Dinosaur based oil" a long time ago. so that's what I have been doing.
He uses only the Napa Gold or Bosch filters.
For the last 25 years, I have been running Delo 400 15w-40 in the Cats (On the boat) as well as all my vehicles and generators, petrol and diesel
with no problems.
I have not switched over to full synthetic oils on the Rangies as I have had issues with it sneaking past main seals on a goodly number of
stationary power plant diesels. Any issues found by others?
