As we discussed I'm up your way somewhat often, always happy to meet up, chat and/or compare notes. Don't think you could have chosen a better land rover platform, but like many on here, I too am biased towards it.
Oh, and I'm running 15w40 mack oil in one of the engines at the moment instead of the Rotella as an experiment recommended to me by an Isuzu commercial guy here who has been with them since the 4bd1 came out.
"Mack Engine Oil EOS-4.5 is available in 10W30 and 15W40 weights and meets Mack’s stringent EOS-4.5 engine oil standard, which offers protection above and beyond the new American Petroleum Institute (API) CK-4 specification by requiring enhanced performance for oil oxidation and oil aeration control. It is also formulated with a lower viscosity, helping improve fuel efficiency, even under high loads and high ambient temperatures.
Mack Engine Oil EOS-4.5 can be used anywhere API CK-4 oils are recommended and is also fully backward compatible with all API CJ-4 applications."
I'll keep you updated as it goes along and when next I change I plan to have it tested to see how it has gone in a bit more detail.
