Spark plugs

With the high mileage and all, the van does go through a bit of oil. I tend to use the thickest I can
find like 20w50, although it does tend to make winter start ups a little tough. In the coldest months of winter i switch to 10w40 , then back to the thick molasses. One problem with burning a bit of oil is spark plug fouling. I am now replacing plugs every 12 months or so, about 10,000 kms. Bit of a hassle but I just throw in some cheap Champions and off we go! These suckers do not look happy.
