Moble 1 for me, here is a saved message about oil from another list I was on that I thought was interesting:


Dear Glenn and List,

I am a chemist with extensive experience in synthetic lubricants. I would
strongly recommend waiting to close to 10,000 miles prior to putting in
synthetic to allow good seating of rings, bore and bearings. Give it 2-3
changes of mineral oil in this timeframe, THEN install the synthetic. Don't
believe what Mobil 1 says about breakin periods not being necessary; you want to
PROMOTE wear to smooth out microscopic peaks and valleys which are still
present even after machining with the most precise tooling in the world. You
have to think in terms of what is happening on a molecular level! 1,000, 3,000,
5,000 miles isn't really sufficient to wear down these microscopic peaks/ridges.

On your question on of Mobil 1 vs. Redline, without a doubt Redline provides
superior
temperature range performance, sludge removal, load bearing capacity, and
antiwear properties because it uses a polyol ester basestock versus a poly-alpha
oliphin (PAO) basestock. Mobil 1 is based on a long chain molecule, Redline is
closer to a microscopic "ball". The ability of the "ball" to roll inside bearing
surfaces vs the ability of the non-branched chains to slip by each other is what
gives the Redline basestock its superior performance, especially since the
additive packages are basically the same.

On the practical side, Redline costs almost 2x more, at least for me (perhaps
others on the list can get cost estimates for Redline from around the country; I
haven't found a good price in NJ). Since I follow the Ford drain interval
recommendations of 5,000 mis, I personally run Mobil 1 in my '95 Contour SE. I
could run longer drain intervals now that I am out of warrantee, but I am
obsessive about my car and go with the shorter drain interval.

Hope this helps!
