Extinct, would you please explain bypass bleed through?

 

Here you go:

 

Thanks for that Extinct. I never really understood all that before.

 

You would have thought they would have learned their lesson the first time but they didn't and they put the same style thermostat on the new 5 l engine

 

It’s not just LR that uses this system. It probably works really well for 8-10 years. After that the manufacturers don’t care.

 

This is an increasing true and bothersome statement. All those new transmissions, t-cases, diffs and hubs that have "lifetime" fluid/lubricant. All that actually means is they consider the car "end of life" when the fluid needs changed. If you plan to actually drive the car 2,3,400K miles like we all aspire too, stick to your dads maintenance schedules.

 

I would say it applies more to the plastics than the fluids. Many of the oils are now full synthetic which will last the lifetime. Our D2's came filled with full syn diff and tcase fluids and should never need changing. We typically run industrial machinery for 3-5 years 24-7 without oil changes. Full syn fluids don't typically suffer the same viscosity breakdown that traditional oils do and they have a higher heat resistance. Plastics on the other hand - much worse. Wide range though across manufacturers. MB is not as affected, LR, BMW, Chevy and Nissan have horrible plastics.

 

Sorry, but not so much.....Here's some "common" knowledge from within the Automotive industry. The Industrial world is a completely different world, and the lubricant technologies do not always directly correlate

 

We will agree to have a difference of opinion.

 

Cool... for those willing to consider information from highly educated sources and leaders of the industry, here's another one on the subject from a couple guys that know more than most of us could ever dream of concerning lubricants in the automotive world
