I believe his information lacked nuance and context, hence overly opinionated and lacking clarity. It’s not a true statement in all situations, even if it could be true in some contexts. Do premium octanes have more detergents than 86/87 unleaded? Maybe. Depends. That’s the harm with making...

Some premium brands, such as Shell V Power, claim to have their most potent additive amounts in the higher octane. Iirc? Someone correct me if I’m wrong. All of their fuels may be Top Tier, but their V Power supposedly has more of the goods. Now, is it necessary to purchase 93 over 87 octane...

Their 0w-30 is rated almost as good as their 0w-20; per ASTM D5293 at -35C https://amsoilcontent.com/ams/lit/databulletins/g2880.pdf So, yes, it has pretty good “pumpability”; technically not “flow” down to that temp. And that’s to the points other members above such as @kschachn and @Pablo...

Of course, good points. My comment was meant to be in the context of an apparently fully drained down top end overnight; due to no ADBV perhaps leading to more dry starts. I could have it conceptualized wrong, just seeing if there were a way to validate the comments of the tech believing it...

It would appear that the dry start condition could potentially be improved with said better pumpability. A 0w-30 with very good base oils could do this better than a low end 5w-20. ;) So, not necessarily a “20 vs 30”difference in of itself.

I do wonder if being able to experience engine temperatures would make the results more conclusive.

I think this is fear based on the old truth over-swelling did occur. Is there proof it still occurs today? Some use HM oils early on and maybe swap back later, but even if leaks occur afterward, is that alone proof that oil is the cause? Inconclusive at best most of the time I’d say.

I do think it’s valuable to remain curious and avoid true conclusions regarding general statements. I drive a 2007 Honda Fit that began consuming oil around 200k miles. Is it just from engine wear and having to drive these engines at higher RPM; thereby increasing the potential for blowby? My...

Well, oil is pretty cheap when it comes to cost of ownership. Based on what the OP is considering, I give the edge to Amsoil SS and jumping up to a 30 grade as others suggest. I’m sure ESP would do the trick too, but the OP asked between Red Line or Amsoil. If ever late on an oil change, the...

Well, on that aspect I do believe Valvoline’s stated approach is to avoid overloading an oil filter. They certainly could push an oil that will clean more aggressively; such as their Premium Blue Restore not designed for use as a PCEO. Too aggressive is too aggressive. But to @tired &...

Ah, thanks for sharing, I had forgotten @wwillson ‘s experience. I recall some members noting oil consumption changes switching to R&P, that didn’t apparently have much in the filter. I suppose it isn’t related to the ring area in terms of cleanliness; as users of that oil have reported...

Cleaning that specifically is something R&P is doing and from my understanding is a more exclusive thing. Eliminating/reducing drastically oil consumption; from apparent piston ring deposit removal, seems to be a thing it’s doing and appears to be an exclusive oil for doing just that. Other...

But, again, it’s speculative in nature. Most active users that contribute do not seem to be using Amsoil SS. The engaged members actively trying HPL is noteworthy as it’s the popular forum darling; alongside R&P. Again, it’s a trend but not an actual comparison as if we’ve got carboned/sludged...

Eh, seems mostly anecdotal at best. Here’s the thing, most Amsoil Signature Series users, are usually over-maintaining their vehicles and regularly use it. As you indicated, what is there to clean? HPL getting popular and board members trying it in droves is something I don’t know if has...

Just comparing the two boutiques… HPL PP has a lower cSt at 40c and 100, so perhaps the oil in general appears to be thinner; which may help the pour point at the colder temp. (Slightly different base oil combinations along with VII, hard to know the percentages let alone the recipe) OTOH, the...
