I can't imagine that Mobil 1 would hurt anything. I worked with a master mechanic in FT Worth that used would save the Mobil 1 from one particular custumer. He was an retired Navy Admiral that babied his 350 and changed it every 2500 or earlier. The tech would run it in his souped up GTP Grand Prix. Then save it run in his wife's CTS. for 3K each. He never had a problem. The first time it was drained it still looked like new. The second time it was still golden.
