Just use Valvoline Premium Conventional

[Mystic]

I noticed that a couple of posts here concerning Mobil 1 got locked up. I don't want to get this post locked up so I will avoid all of that stuff as much as I can. But it does seem to me that if a synthetic oil flowed at -55 to -65 in the past and now flows at only about -38 that something has changed. Heck, Pennzoil conventional will flow at about -35 or so. So I figure perhaps a person should just use conventional oil. I can get Valvoline for 10 bucks or less per 5 quart case. Add a little Valvoline synthetic oil treatment (about 2 oz.) and 3 oz. of Auto-RX to keep the engine clean and maybe you have a winner. The Valvoline engine oil treatment would last for a few oil changes.

In the wintertime I still would want to find a synthetic if I could. Maybe the 0W30 Mobil 1 still flows at a low temperature. Or maybe use Pennzoil Platinum. Maybe just use a conventional oil if the conventional oils flow about the same as the synthetics today.

From the one locked thread started by bobistheoilguy...a post by MolaKule:

A paper from LE of November 2000 makes comparisons about various esters and the lengths of the molecular "chains."

They found that the better esters (meaning ester with lower coefficients of friction) had longer chain lengths.

So how does this relate to the discussion?

"The longer chain forms a better surface protecting film and allows for a lower coefficient of friction.... longer chain lengths ALSO INCREASE the POUR POINT."

Check the pour points of some of the synthetics. Some of them still have really low pour points, but not as low as they once were as MolaKule explained one possible reason why. The other reason is some synthetics use Group 3 in place of PAO or use some of both.

VSOT and Auto-RX may be a good additive blend for conventional oils but don't expect it to turn conventional oils' total performance into that of great synthetics. That performance difference is rarely witnessed by most drivers because they don't abuse the oils enough for it to show itself. Those people wouldn't even have a need for the VSOT/Auto-RX blend.

please dont confuse refined crude oil, conventional mineral oil, with synthetic based oils, even though big oil is doing a great job at confusing people, this may help confuse you more or help you see the clean oil.

One more thing. Supersyn Mobil 1 oils all use small percentages of very high viscosity PAOs which do NOT have super low pour points. Check the pour points of the M1 lineup. Some of them are still very low, despite these PAOs being used. Your engine does not know what pour point is though. The cold cranking and cold pumping specs are what counts in sub-zero temps. The pour point and those specs are not directly related.

For $1 more you can get a 5 quart bottle of Maxlife; the creme dela creme.
