Most 15W-40 oils are junk though. If in the API realm, I'll take a 5W-30 or 5W-40 over a 10W-30 or 15W-40 regardless of temperature.

Yes. Every oil does this due to oxidative thickening and soot/contamination loading. Oils that show a lower viscosity in UOA are doing this too. If an oil starts at 10.5 cSt and shows 10.0 cSt after 5k miles and no dilution present, it likely sheared down to 9.5 cSt (or lower) before...

Yes. I touched on that later in my comment.

First off, let's define what octane is. Octane is a measure of the auto-ignition point of the end gases. It is NOT a definitive measure of knock resistance in an internal combustion engine, as I will explain later. The addition of 10% ethanol will not have a substantial impact on RON. This...

A beautifully marbled prime NY strip, aged 30-35 days, cut 1.5" thick, seasoned simply but liberally with salt and pepper, and cooked medium rare in cast iron with Kerrygold garlic and herb butter.

Welcome to the club.

The majority of oil supplements are snake oil. The few that do contain beneficial additives are often blended in a cheap bright stock or polymer with poor oxidation resistance and heat tolerance with no guarantee the additive content won't clash with the additive chemistry already in your oil...

No. I don't condone using singular UOAs as conclusive data, and I hate that he does this. He knows better, we've spoken about this, but in the world of Youtube, there's often a distinction between what's valid and what's likable/relatable. Lab tests like PDSC, TGA, RPVOT, Teost, etc... and...

No. This video is just beneath the average BITOGer. Take it for what it is. We are not the target audience.

I will defend him here. He's very knowledgeable when it comes to data and the proper methods of obtaining that data. However, most of it gets lost on the average Youtube viewer. That stuff makes videos dull and boring, unlikey to be shared, and so on. I don't like that he does it that way...

The 0W-20 will be fine by itself. The BG is just making your wallet lighter. BG 115 has a KV100 of just 7.7 cSt (likely lower viscosity than your 0W-20) with a pour point of just -25°F and flash point of just 355°F. That's making your oil worse. Ditch it. It's highly unlikely that your oil...

I correct people at times outside of BITOG. The issue I commonly see is people mistaking the "W" in a multi-grade to mean "weight" and thus want to say the first number is the oil's "weight." I see it almost daily in some car groups, especially older classic car groups, people thinking a...

Under the API umbrella, conventional oil does not clean any better or worse than synthetic oil. That's a general statement. There's exceptions such as Valvoline Restore & Protect. The same applies to seal conditioning. Conventional will typically contribute more deposits and varnish due to...

Sometimes people inadvertently create the very problem they're trying to prevent. Arbitrarily increasing viscosity due to high mileage is a prime example of this. When you go up in viscosity, two things happen. Flow decreases (slightly, more strain a PD pump to move the same volume) and...

You can ignore anything posted by 540rat. It's pseudo-science. The oil used by Sprint engines, turning 9000 rpm with 910+ HP on methanol and 300°F oil temp, performs rather poorly in that test. Think about that for a minute. if you ran Head and Shoulders through his test, it would shoot to...

Those parameters are how OEM engineers decide the appropriate grade. It's based on HTHS but presented as a grade since it's more publicly familiar. The worst case scenario is factored in that decision. Also note that I said most engines would see no benefit, not all. As with anything else in...

No. There's 3 factors that determine the ideal oil viscosity/grade. 1. Operating oil temperature 2. Rod and main bearing clearance 3. The load on those bearings None of those variables are changing with high mileage. If you do wear the bearings enough that the clearance warrants a jump in...

They're the CountyLine brand from Tractor Supply...

I keep a mix of 75/25 acetone/ATF in a spray bottle for that purpose. As has been stated, a 160°F stat is undesirable for anything other than (maybe) a drag car. The lower temp means less cylinder and intake heat to vaporize the fuel which means more fuel wash of the cylinder walls, reduced...
