Hi

I have a willy 3 with around 105k miles on the clock. Now, when the engine is cold the oil pressure is circa 4 bar on idle rising to 5.5 - 6. I was stuck in traffic for about 30 minutes after a drive (not a particularly spirited one!) and the oil pressure gradually fell off the scale. Its still high when cold so I don't think there is a pressure probem per se but obviously when its hot its very very low.

I looked at the oil when it was hot and it was so thin - almost like water. I assume the oil needs to be a bit thicker but not sure what to put in. Does anyone know of a thicker oil that is used and if so what is it? has anyone else had this porblem?

Thanks

Ben
