The hemi has 4 lifter oil galleries,that each feed one set of mds lifters and one set of non-mds lifters.The mds solenoids restrict oil flow to the lifter bores when mds is disengaged,basically starving the lifter bores,which has been known to lead to lifter scuffing.
Listening to what you are saying man. Appreciate your posts. I dont hang around here much at all any more but used to live here for a handful of years. Had to come look after what My man Mike was sayin.
MDS has been around from word go on the 3rd generation hemi engines.When they brought the hemi back in 03 it was designed with MDS in place.The 5.7 heavy dutie trucks didn't employ mds until i think somewhere around 13 or 14,and all 6 speed manual transmission Challengers are mds delete,but all 1500's have had mds.
Is this in a 5.7?
I checked a few sites and summit has it for 15.99 a quart! Dang stuff used to be like 11.49. Ive seen a few nice looking UOAs with porsche engines as it was developed specifically for those engines but on their website it says "compatible with german, british, and italian sports cars as well as chrysler 6.4 hemis"Listening to what you are saying man.

Good stuff brofessor.
Question,
Anywhere else I can find this for way less than $19 a quart? If not your off your rocker….hard to argue with 11.89 a quart of SS0W40 but ill put my money where my mouth is at the end of this OCI. And if its not good….ill change. Im not a fan boy of any oil anymore
Nice to meet you sir

Ill try and ask them for a pds to
Sure is lovely!
Yes, I spoke with HPL and they advised this oil. Truck has a high lift cam, and a 6.2 oil pump, with non MDS lifters
...and look at that Azufre! 0.400!! (whatever the heck that is...lol!)
Lovely! I debated on using it to! They developed that oil against mobil 1 FS 0w40. They had less wear and a lower coefficient of friction than mobil 1
I had planned to run this oci to 7500, then the next send a sample out at 7000 to have it looked at.
Sounds like you got my dream setup if i ever need a cam
It's fun! I changed mine last year. Before it could go lol
You can generate the same idle pressures with the stock pump,by upping the idle rpm to 750 rpm.The cam lobes and lifter rollers are still lubricated by the oil flung off the crank,as there is no pressurized oil fed to the lobe or wheel. My truck hot idles at 51/52 psi,and runs down the road at just under 60 psi with the stock pump and dual remote filters.
I believe my idle is set at 750-770 currently. Would have to ask my tuner the specific spot for it.
