They don’t recommend an HTFS. They added a timing chain wear test on a 2.0 EcoBoost, and that was the result - with the bare minimum add packs used in shelf oils - the SP formulations ended up with slightly thicker base oils to pass the test. Race to the bottom, cheapest way out…

Not so much. Oils are formulated wildly differently. Most 5W-30 SN oils had HTFS in the range of 1.8-2.1. With SP, that’s now 2.1-2.2 to pass GF-6. In the case of HPL no VII, HTFS = HTHS. So 3.x… Lot less work for the add pack to do. Also, with GTDIs that have dilution, the lack of VII for the...

The older 10W-20 Formulation was 2.84, IIRC. At the time, the no VII line wasn’t even a thought probably. In my case, it made particular sense as the engine I had is prone to significant fuel dilution (which the 10W-20 is highly resistant to) and it had no VII for the fuel to break down...

If you are using it as opposed to a 30 weight due to the HTHS.

They currently offer a 5W-20 no VII if your application calls for a 5W-20.

Most likely could have done more. At 7500 miles, it showed 3 points up on oxidation and nitration, viscosity was 8.1 cSt (VOA was 8.4). Fuel Dilution was ~4.5%. TBN was 7.81. And wear numbers were 1/2 what most users using a shelf option were seeing with intervals half as long! So I have...

Starter drag when cold will be the stopping point on the 10W-20. MRV is similar to most 5W-30s. How it performs used… is anyone’s guess. Most oils suffer dramatically reduced cold start ability from fuel dilution, combustion byproduct accumulations, etc. Those guys maybe have tested a used...

The 10W-20 performed exceptionally in my Mazda CX-9!

Unfortunately no. My assumption is that between leaving Japan, and getting to Cleveland, it saw significant idle times. I generally run a new engine ~300 miles, and change oil. I carried this one out, and made an interstate run for a large portion of that, cycling up and down the RPM range in...

My initial sample had 4.6% in 211 miles. I nearly had a heart attack!

You’ve seen my results on my Mazda - I run Top Tier 93 consistently - I have over 4% fuel dilution on a normal interval. Then again, the factory oil lost 15% of its viscosity from 4.6% dilution, and the HPL lost 3.5% @4.3% and still has about 8% of the original fill affecting it! I was told at...

2.86. 2.9-3.5 is a U.S. 30. Older Euro 30s will be 3.5+. Factory Mazda fill is 2.94. It also has significant dilution issues. Seemed like a great option for my application! The HTFS goes from the SN factory oil at 1.9, to about 2.7. My wear trends so far would play out that’s probably...

This is because there is more VII additive in the 0W-20 with a thinner base stock typically - that hurts HTFS - and so valvetrain, timing chains, and ring/liner interfaces where full temporary shear occurs, will have higher wear rates. Finding a 0W-20 with a relatively high HTFS and relatively...

The CCS will be the limiting factor for cold operation - and while it can get below 0 on occasion here - in the 3 years I've been here, haven't seen it yet! IF that happens - I'll park in the garage next to the apartment - where it will be significantly warmer due to heat from the building. MRV...

Define "short"? If I take it to work - 7.5 miles - 11 stop lights, 4 stop signs - no limits above 35 - hilly terrain (NEOH) If my wife drives it - 2-5 miles to "town" for whatever she needs, and back. Aside from that, generally we take it on any longer trips, usually at interstate speeds. The...

So, right after buying it, I went looking at UOAs for the engine - tons of 5W-30 Blackstone reports showing KV100 in the 8s… that screamed dilution to me! I discussed this with @RDY4WAR - he agreed that looked a bit suspicious. That lead to me asking if he knew of an oil with a roughly 2.9...

Of some interest, potentially - I’ve run this spreadsheet on a few different oils, from a few different platforms - some trends show up as I’m doing this - the Magnesium is usually within a very tiny margin of expectations - a couple ppm variance. Calcium is always depleted somewhat (40-70 ppm...

I will respond as I’m using this oil. 2022 CX-9 Signature. EPA estimated economy is 20/26. Most people report that with the AWD models, they are struggling to get anywhere near that. I have a 50/50 split lifetime - hand calculated with Fuelly, and a 24.7 average. When I went to Manteno for the...

RDY4WAR generally posts my reports. I created an account at his request, and have started to participate some here. I found it helpful to eliminate some background noise in the raw data. Is it perfect - probably not - but it is a lot closer than looking at the raw numbers.
