The oil has been changed with Chevron Supreme 10W-30! Much to my delight, when I fired up the engine, it did not explode. My lawn didn't turn brown, my dog didn't run away and my computer hard drives did not get formatted. Thanks all!!!

I bought my first car after being separated from military service and entering college in 1966. In that time, I've used 10W-30 oil for most of our vehicles (over 15), with no evidence of a problem of any kind relating to that oil. Most of these vehicles were used, with mileages running from the 30Ks to 180Ks. Some non-turbo, some turbo. I did eventuall switch to 5W-30 for the turbos, on the advice of a mechanic....but I never had any problems with the 10W-30 I used previously. As for brands, Kendall, Quaker State, and Pennzoil. It should probably be noted that all these cars had O&F changed religiously at 3K. My total lack of engine oil - related problems would appear to indicate that these are pretty good lubricants for our environment (central IL).
