So, I made a thread yesterday about Motorcraft oil being noisy in my 2.5L Escape and how VAS/SynPower made it noticeably quieter. What I didn't mention is that whatever bulk oil came in my Vic was quieter while after putting in the same oil as the Escape (VAS/SynPower) it's a tad noisier. I was planning to standardize my oil across all three vehicles but I haven't changed the oil in the Suburban yet since I pretty much don't drive it, though I'm tempted to because I'd be curious if the VAS/SynPower makes any difference in noise in that one compared to the Chevron Supreme that's in there now. I just want to minimize how much oil I have on hand and I picked VAS/SynPower because it's name brand, quality, and available for about $22 on Walmart or Amazon and always in stock.
TL;DR: What really I want to know is if less engine noise = better wear protection, or just that different oils have different properties that change the noise.
