I have a couple of Ford Explorers and have just helped a friend buy a Jeep Grand Cherokee.
I run an adventure tour company based in Morocco and the vehicles see a great deal of use in the Sahara. Summer temperatures are well over 110 degrees F, along with heavy dust.
The book for the Explorers recommends an 10w30 oil, which is not available here. I have a BMW which runs perfectly on Mobil 1 0w50, but this makes the cam chains rattle on the one Explorer I tried it on! On 10w40 the chains are quiet and it uses no oil. On 40 monograde it used a litre of oil in 200 miles... on 10w40 it uses nothing with 3,000 mile intervals.
So - are there any alternatives?
And what should we be running the jeep on?
All advice is very welcome.
