Thread: Engine Oil. Change intervals.

I did the next change after 5K using Valvoline again with a new filter. Last weekend I did another oil and filter change and used a Nulon product of the same viscosity and grade but half the price. Something odd I've noticed with my fortnightly oil level checks when I get fuel is the oil takes nearly a thousand k's to get dirty. Every other diesel I have ever had made the oil filthy in a very short time, even the 2012 BT50. Am I missing something😕 The Disco doesn't burn any oil...though it seeps a bit😆

Waste of good oil, LR says 10K, oil makers say 10 to 15k, give the oil a chance to earn it's keep, regards frank.

What he ^^^^ said, I use Penrite oil and change it every 10k.

nulon, penrite and castrol mineral base oils are good for 10K intervals if your engine isnt making metal or suffering excessive blowby or generally being abused.

you didnt mention it but generally if you know what the expected oil loss/use is its more important to watch the cooling system like a hawk on the tdi(x)00

Thanks for the input When I did my research on the Disco's I read a lot about the 300 Tdi re cooling system. I decided on the D1 because of its simplicity. I've read some horror stories about overheating

yeah, its odd, every one bags my disco at work...

its spent the least amount of time in the workshop out of all the other vehicles present. and that includes 2 full engine services and no work done at home.

Mines done every 5k as I have the fuel wound up a bit and dirtys the oil up quick
