Engine oil....help needed on choices

.... Depends on what ya been burning up til now . I switched from a paraffin based eastern crude to Castrol in a truck (86 GMC 305 cid) and it started burning oil because the oil cut the paraffin based crud/deposits from the valve seals . Replaced them while I had it down for a timing set R&R and all is now well . +1 on the paraffin-based. Had old Chevy 350 plug up the return holes on 7 and 8 cylinders from the crap one of them left in the upper valve covers -- was one of the early pollution-control systems and consequently ran hotter than earlier of same vintage; was the death knell for it. Rebuilt with new mains and all and did the switch to Castrol and it did another 250K before donating it to one of the charitable contributions outfits... -- |

After sitting with 1990 oil in it for 25 yrs..simply changing the oil without a flush of the engine with diesel fuel instead of oil..allowed a **** ton of oatmeal to remain in the engine and plug up all the oil ports and passages. Which required a rebuild, crank regrind, new rod bearings etc etc after having the engine dipped. 4000 miles and it ****ed all the important moving parts up.
