I bought it from an engineer with serious OCD who kept every record and only used 5w30 oils. Thanks for all the advice. I'm going to try the Mobil 0w-40 fs with the next change. Curiosity, great HTHS, great PSI ratings from (504, rat), and reputation make the change worthwhile. You're probably right that the engine won't notice but it will make the driver think he did something special for the old girl.
By the way, take this test with a grain of salt. The biggest grain of salt you can find.
