Don't be discouraged by the worries of the thinner oils. Your car will have been replaced before that difference (if any) would show itself. My '95 Chevy 5.7 has 210,000 miles on it with 0w-20 iused in it since around 20k miles. My change intervals are 10k for a filter and 30k for everything. The truck doesn't use any oil between filter changes and has the probably never been driven without seeing full throttle. The truck will likely rust away before the engine dies....
