I live in Switzerland and it seems that 5W-20 oil is hard to get over here. My Ford garage recommends to use 5W-30 with my new Lariat.
One oil importer also said that in Europe the speeds are usually higher (I guess referred to Germans highways -- NO speed limit) so I should use a higher viscosity oil like 5W-30 or 40.
Although I don't drive usually very fast about 50 to max .70 milesph on the highways. I think my driving style is more "stop and go and stop.."
Can anyone help?
I will also be changing to Mobil One Synthetic 5w-30. Only I am waiting until the first oil change at 3,000. I read somewhere that it is good to use conventional oil for the first 3,000 to let the gaskets seal and such...
I switched to mobil 1 5w-30 at 3000 miles. No problems at all. The engine runs just a hair cooler and even runs about 250 RMP lower believe it or not. Before you change oil, look closely a all your gagues, then look again after oil change.
