Synthetic "Blends"
Only this comment, as I, too, am a firm believer in frequent oil & filter changes AND the use of synthetic oils: the so-called synthetic "Blends" are, indeed, only part synthetic... Maybe 20-25% synthetic (if that!). Do the math: if they were 50% the mfgrs. would charge at least 50% (plus some % + $) the price of the 100% stuff. I have no doubt what-so-ever that blending is superior to conventional oil and is the smart way to go with oil change intervals in the 3-3.5k mile range. I use 1 quart of 100% synthetic with 5 quarts of the same mfgrs. "blend" OR 2 quarts synthetic with 4 quarts of the same mfgrs. conventional oil. I bought 4 cases of Havoline 10W-30 semi-synthetic on sale at $.41 per quart last time it was available. This works very well in my SVX, a Ford 3/4 ton with a carb 460 & in my wife's Mercedes V8, too. None has ever even had the heads off, much less needed attention in the bottom end. I would like to hear more about synthetic trans fluid choices & prices...
