Thread: keeping on top of servicing

If the "synthetic" is not marked PAO or Ester base, then its simply not synthetic, its a play of words, a legal loophole in the way they crack the mineral oil molecule that allows the oil companies to label mineral oil as synthetic.

Also there is no minimum quantity that an oil company or oil blender need to add to an oil to again call it synthetic.

and also oil blenders will make a big song and dance when their product is an actual full synthetic engine oil, so if no snake oil sales pinch then you can be sure its not an actual full synthetic engine oil.

Thanks,

Coolants have progressed a lot in recent times. I’m going to do my D4 shortly at 7-8 years versus 10, but not because I don’t trust it, I want to change a hose and plastic outlet for continued reliability so will change the coolant at the same time.

For Discovery 3/4 We normally include a coolant flush at the timing belt service at 168k - 182k (depended upon engine) I would strongly recommend the exclusive use of Genuine Land Rover Coolant. Brake fluid flush is recommended every 3 years.
