Hi, I'm new here looking for information. I found a reply in a old topic that seem to discribe the problem I'm having with Valvoline Maxlife blend. Originally Posted By: ARCOgraphite Less traction on the M1 PAO base may lead to increase tappet noise, as the dynamic oil wedge is lessened under the tappet foot. What? Please explain that for me as i do not understand traction, dynamic oil wedge, tappet foot. Given lubricant of non-diverse, short wax chain length and a likely lack of vii the oil doesnt wrap around the camshaft like 'honey on a spoon' and provide an (overly?) thick oil cushion for the bottom of the cam tappet to ride on; instead its riding on a near monomolecular layer of lubricant or boundary or EP. Typical of PAO base syn with no vii. May cause more metal scavenging by EP ADDS v. your old fashioned conventionl, molecular diverse 10w-40. My 97 Ranger 2.3L seems to have more valve train clatter with Maxlife and I've read Valvoline has removed moly from Maxlife. I've always used Valvoline in all my vehicles. Now I'm looking for a off the shelf 5w30 oil brand that I can buy at Walmart that has the additives needed to make the oil cling to parts and keep my engine quiet. Is there still a brand or type of oil that will be good for this ? Thank you.
