Needed a couple of items from the local Auto Zone. With a case of Castrol in hand - I happened to see they had (HAD - key word - I bought all 8 containers!)
DelVac 15W-40 for $6.69 per GALLON! That's cheaper then the "generic" quarts!

No - it's the regular DelVac 1300. He also recommends it! IIRC - He says he uses this to break in engines prior to changing to the synth.
I am leery about changing to synthetic - both my P-cars have been on the regular stuff too long.
STILL - A great price on an excellent oil.

What were you running before? Smart choice on the Delvac, although I believe that the 15/40 is a diesel application, which should have more detergent levels. This may mean that as it 'cleans up' the deposits left behind from your petroleum based oils, you may need to change the oil more frequently the first few times (every 1-2K's). Then switching over to a synthetic (clearly better flow dynamics and protection) should be no problem. I'd consider the 5/40 wt if you're interested in doing a little homework. Just get on the Mobil site and do a product spec search for 'Delvac'. All the viscosity applications will come up and you can compare the following...Visc@40, Vis@100, HTHS Vis (should be between 3.5 and 4.5), Pour Point, Flash Point, NOACK (Ideally less than 6%), and Viscosity Index (greater than 150). All that being said, I think you'll find that the 5/40 will give you better cold start flow and theoretically better bearing protection, while at the same time provide just as thick a film at high temperatures to give you an acceptable HTHS value.
Best searching...I've gone to RedLine 5/40 (www.redlineoil.com), but in no way am trying to sell anyone on the stuff. Hell, my mechanic thinks I've gone off the deep end...perhaps.
