This is the last thing I thought of when I bought a case of 12 ACDelco PF63E's for a Silverado with the 6.2L V8 L87. Long story short, I sold the Silverado after just one oil change (for my 6.7 Cummins powered Ram,) and now I have a case of 11 of these PF63E oil filters left over. I have one...

You certainly don't get any advantage when you are comparing the Rotella T6 products, 5w-40 vs 10w-30. I agree, I like the better protection of a 40-weight oil (over that of another 10w-30 say from Valvoline,) and it can be acquired much easier than the 10w-30. The factory grid heater is...

The 15w-40 is the standard fare in the GM 6.6L V8 Duramax diesel and an option in the Ford 6.7L Powerstroke, but with the hydraulic lifters in 2019+ Cummins specifically says not to run the 15w-40 oil. It gets below 0 degrees for just 3 months? Remember, the Cummins via the owners manual is...

Yes, the motor and the vehicle is new and still breaking in. My preference is to find an oil the motor likes and that provides for adequate protection, which is why I dumped manufacturer spec ACEA C1 5w30 for an ACEA C3 5w40. I wanted a higher HTHS while still being cognizant of my SCR and DPF...

I think I may have figured out the anomaly on the wear items. Hot Shot's Secret FR3 Friction Reducer. https://www.hotshotsecret.com/fr3/ When I went with the HSS Gray Diamond Euro 5w30 I didn't quite fully realize that it already contained their FR3 friction reducer. I later read somewhere...

Interesting. The motor otherwise runs stout and purrs like a kitten. I found some UOA's from some F-150 3.0L Powerstroke motors and Cu was not near my levels. My MY20 Lion Td6 should have been assembled with the latest improvements to the product line gleaned from the F-150 development...

I don't believe any of the diesel additives have Cu in them, no. Even if they did, I don't know how they would make it into the oil if I wasn't otherwise experiencing fuel dilution. Per Blackstone Labs, copper usually comes from brass or bronze parts, copper bushings, bearings, oil coolers...

I didn't want to run a CK-4 oil in my Land Rover because of the potential sensitivity of the SCR/DPF system. I liked the ACEA C3 oils with their 0.8% max SA content. Originally, JLR tried to say you should run an ACEA C1 5w30 oil and that's why I dumped that at 2k miles. I don't think many...

I only did 8.2k miles on this OCI so I'll look to do slightly less next time, maybe 7k and measure the TBN, and maybe the TAN as well like you say. I have enough of the same Motul oil to do another oil change, but obviously, I'm on the fence right now. Is the shearing of the oil indicative of...

The factory fill Castrol 5w-30 was changed at 2,000 miles. I went with Hot Shot's Secret Gray Diamond Euro 5w30 which is an ACEA C3 oil. I wanted to go to a 5w40 based on my experience with my previous Jeep Grand Cherokee EcoDiesel, so I went with Motul X-clean Gen2 5w40. Ford F150 owners manual...

Wait, what? QS Euro 5w-40 is an ACEA A3/B4 oil; SA ≤ 1.0 and ≤ 1.6. That's not even a mid-SAPS, that's like a full SAPS. I find it interesting that the MS-12991 is an ACEA A3/B4 oil with full SAPS. Seems like an odd choice given the DPF. In 2016 FCA first went to the MS-11106 which was an ACEA...

LM is good but not great. Ravenol specs are usually superior and can be had in the US via Blauparts.com.

10% volatility for an oil that advertises itself as a direct injection oil - that's ironic. 10% isn't bad, but I'd like something in the 6-7% range, or lower.

Ravenol VollSynth Turbo 5w-40. BMW LL-01. Look at the specs. If you find a better LL-01 5w-40, let me know. Order yours at Blauparts in Wisconsin.

Compare the specs, won't find a better one out there than Ravenol VST 5w-40 or RUP 5w-40.
