My sarcasam wasn't relayed through the internet. it's 'Algore's' fault.

Anyway, to the subject at hand, I have no idea what the PO used in the 99 astral but it's all still in there after about 1200 miles (except the damn dipstick is ridiculously hard to tell with... Looks like Guinness at every fill-up on the stick but clean on paper. Brilliant!) Since our other two cars get Castrol Syntec 5-50, I'll probably start buying it by the case (Eek! $6 a quart not on sale... Gulp!!)
I tried Mobil 1 in a 20 year old 240sx but it kept eating the stuff at a quart every three months. Royal Purple was worse!!

Anybody dig Castrol for their yahzu?
