Michael,
This ad pack covers many additional specs. It is not Porsche C20 nor VW. It does cover things like ACEA A5/B5-21 ACEA A7/B7-21, GF6A, BMW LLO4, BMW LL12FE, MB 229.51, 229.52, 229.61, 229.71 and JLR 03.5006

Thank you.

Couple questions:


1. Are you concerned about warranty issues by using an aftermarket oil filter?

2. Is your 3.0 still not burning any oil? I’ve seen many complaints from owners about oil consumption in these engines.

No concern about the oil filter.

The engine has consumed 1/2 quart in 10,000 miles. Oil consumption is caused by the volatility of the 0w-20 oil. HPL is going to make a less volatile oil and we’ll see if it reduces oil consumption.

Thanks. I was thinking that as well.

Have you considered using a synthetic C3 5w30 or even a HD 10w30 to see if oil consumption goes down or stops completely?

I want to stick with the Dexos D add pack, so HPL will have to blend a 5w-30 or 10w-30 with the proper additives. If it reduces oil consumption, it could be a great oil for those with the Duramax 3.0L that have oil consumption issues.

any updates? Have a 21 with the LM2 and 69k miles and use M1 but looking for a reason to support HPL. Lol

And since this just popped up again, have you gained enough info on your Banks IDash to give us a review yet?

Not enough miles yet. I'll updates when I get to 10k miles on this run of 5w-30

Yeah, I just need to get to it. Standby.

It's been a few months now. Any updates on this?

This run of HPL Dexos D 5w-30 now has 12k miles, the same mileage was with the HPL 0w-20 Dexos D.

The consumption was exactly the same at 12k miles comparing the 0w-20 vs 5w-30, 1 quart.

My prior hypothesis that the lower volatility of the 5w-30 would reduce oil consumption was wrong. The volatility of the 5w-30 is about 50% of the 0w-20 and it still used the same amount. The type of miles are very similar between both runs. 90% highway miles and 10% in town.

Oil consumption doesn't seem to be related to volatility. I have taken several temperature measurements with my IR thermometer at the oil sump and I don't think the oil runs nearly as hot as the iDash says. I will see temps on the iDash of 245°F cruising down the interstate. When I stop and shoot the pan I see temps around 200°F. I wonder if the oil temperature read by the iDash is estimated like it is in the 6.6L Duramax?

Where is the oil going? I have a very good clue.

I took these pictures inside the aftercooler with my bore scope. There is oil sitting in the after cooler from the CCV. I believe these 3.0L engines may be ingesting oil because of the CCV design.

I have installed a VSE catch can. More to come.

What a shame. GM seems to think “just because it’s a diesel, we don’t care about oil consumption” is an anywhere remotely acceptable position for a vehicle manufacturer.

Hope the catch can cures it!

I would really like to run this DPF for the life of the vehicle. Consuming 1 quart of oil every 12k miles and dumping that sulfated ash into the DPF doesn't bode well for DPF longevity. We'll see how much is caught by the catch can, then we will see if the engine as actually using any vs. ingesting.
