I never asked your opinion on IF HDEO was a good choice. I asked if anyone had thoughts on 5w-40 or 10w-30 HDEO as a better call. How about answering the question asked or shutting up? You're a smart guy, but your posts are typically quite arrogant. How about stick to the topic, or start your own thread titled "why 3 valve 5.4s don't need HDEO, and the winters in tennessee don't require synthetic". Then I will start one about the effects of too thick oil on hydraulic timing chain tensioner seals on 5.4 3V engines. Do you just troll posts looking to disagree with people? Thats all I ever see you do.
My apologies; when I first posted I was unable to view the embedded image because I was at work and I have no control over the firewall they implement (and so I unaware that 2010FX4 had posted it because it was blocked from my view). Now that I'm at home, I can see the image. Sorry that I missed it at first. Sorry that my missing it apparently angered you.
Sorry that I took your invitation as a means for all to throw in their opinions; after all, you did state this ...
"Team- ..... Any thoughts or recommendations on brand? ...."
Apparently you've been happy with the 10w-40 to this point, so what makes you want to change to a different base and grade now? Why HDEO? Why syn? What happened (or is about to happen) that makes the current 10w-40 undesirable as soon as "winter" comes around. What happens in TN that is so terrible that your current oil is suddenly unworthy, when it's made you happy up to this point? If you are so smart, then you should be able to clearly articulate just HOW and WHY the 10w-40 is so good during summer, but not in winter. Please educate me with facts and credible data.
Typical of most BITOG posts here, you have not shared with us the criteria you're using to judge this effect you seek; that of a "better" flow at start up. So, given your area and average low temps, what is the mean time to "flow" as measured with your 10w-40? What deviation is typical? How do you even know that a 10w-30 or 5w-40 is going to really be "better" in terms of measurable, quantifiable performance? For something to be "better" in this regard, you must have some data that shows the 10w-40 is going to fail and your engine implode, right? Because to be "better", a competing product must be able to show a definitive advantage that is actually tangible. As we know, when it comes to wear, the mod motors really don't care about grade/brand. And as you've indicated above, the cam phasing is apparently unaffected by the vis. So .....
What is the basis of you needing a "better" oil than the 10w-40 that is already making you happy? Your area is not cold enough to make any difference. Your wear rates are not going to be affected. Your cam phaser is (by your claim) not an issue. So, with just one rational, clear, articulate sentence, please advise us why you need a different lube in the first place.
This isn't about need; it's about what you want. And what you want is for some folks to agree with you so you feel justified in your added expense of syns for winter. I obviously misinterpreted your intent; I assumed you wanted the "team" to contribute. Understandably, now, you simply want others to chime in and corroborate your "need" (aka want) to do this. And those of us who disagree are not to be heard from. My mistake. Sorry 'bout that.
