Elongated Baked Bean
I love pouring Penrite HPR 30 (20w-60) into my XC Fairmont. I've tried going with HPR 15 (15w-60) full synthetic but the motor really doesn't like starting up with it, seems to lose it a bit faster too. I hope I can get away with 20w-60 in the EL's 4L as well, I have a few bottles stashed because of the XCs habit of pumping oil out through the rocker cover gasket.

One thing I was told when I swapped my new motor in just over a year ago is to stay clear of Castrol GTX with a Ford 250 crossflow because it causes the valves to stick. I'm not interested in testing this problem which is a shame because that poo poo goes on sale every week.
