Some on here are getting downright obsessive on engine cleaning. If you use modern synthetic oil of the correct viscosity and oci’s, your engine should be spotless.
I already lost that bet with a BMW that only had BMW branded oil in it @ OLM changes for 120k miles. It had black gunk built up under the VC that HPL Cleaner removed. Not good for that to get in the variable valve timing system.Wanna bet?

3800 is an old engine and oils then were not as good as today's.This came out of a GM 3800 V6 with 130k miles that used modern API oil and changed religiously every 3,000 miles. This was after an OCI with the HPL engine cleaner.

Oils then? We're talking about API SM and SN. It was in a 2005 Buick LeSabre.3800 is an old engine and oils then were not as good as today's.
View @OVERKILL’s oil filter thread that had a diet of solely M1 EP from new… and once on HPL Overkill 0w20, he found his filter caught a slurry of soft, carbonaceous “dirt” that formed something almost like a grease.Some on here are getting downright obsessive on engine cleaning.

HPL sez “hold my beer and pour me in your sump… prepare to be amazed!”Wanna bet?

That HPL oil yawns at me, and sez "is at all you got ?"HPL sez “hold my beer and pour me in your sump… prepare to be amazed!”
In many ways - but OEM’s have ESP standards that not all “boutique“ lubes will meet …The HPL oils , are pretty modern!
Not sure if the 229.5/502.00 add packs being used today are much different than the ones from 20 years ago.This is what I was basing my statement on. 2000 MB 4.3 V8 with 100k and very little info on service history even from MB. I'm assuming what maintenance it had was with 229.5 oil. I was amazed how clean it was for a 22 yr old car.
could you link it again?I looked through his posts and couldn’t find it.
i found it. Very interesting.
You giving up your free LM?I also used 2x cans of LM engine flush prior to draining. I'll likely switch over to HPL Euro 5W40 like my Sportwagen on my next change which should keep things nice and tidy going forward.
Probably true. 229.5 has always met a tough standard.Not sure if the 229.5/502.00 add packs being used today are much different than the ones from 20 years ago.
