Mixing pp and dino

[wingdr]

Since I got a great deal on pennzoil 5W20 at Home Depot, I thought I would mix. Planning on using 2.5 qts dino pennzoil and 2 qts PP in a 2005, 2.4 honda I-VTEC. Been doing 5,000 OCI and just turned 15,000. Have got enough to do 6 oil changes. Any problem doing this? Thanks , Tim

Now that you mentioned this, I find it strange that no Pennzoil syn-blend has been available here in Lower Michigan since the Platinum arrived. Why is that & has it been discontinued .... anybody?....Johnny?

The local WalMart still has the Blend - Pennzoil SUV, Truck, and Minivan. I think someone claimed it has been discontinued.

It works very nicely. I posted a UOA of 4 quarts of regular Pennzoil 5W-20 and 1 quart of 5W-20 PP. Prior to doing this I had the following response from Pennzoil tech support "Thank you for your interest in our products. There is no problem with adding a quart of Pennzoil Platinum to 4 quarts of the Pennzoil conventional oil. They will mix without any problem.
Sincerely
Product Technical Service"

Brent, Thanks for the response. I didn't think it would hurt, but I wasn't sure.

I just sent Pennzoil.com an email requesting if I can blend three quarts of older Pennzoil Synthetic (prior to Platinum) -- with two quarts of Group V Platinum Synthetic?

What are you talking about?!?! PP uses Group III base stocks.

The predominate base prior to November 2005 was supposedly Group V.

There's a thread here somewhere with that info.

Ethylene-alphaolefin polymer (EOP). EOP is synthesized from ethylene, propylene and butene using a single-site catalyst, and the reaction products from the process exhibit comparable physical and chemical properties to PAOs.

Do we know definitively why Pennzoil got away from EOP? Was it cost or was there a problem.

My best guess is volume. I think the sales exceeded the supply.

I think the next big trend in base oils & additives is strictly GTL, so the EOP base oil project got "left on the wayside".

All the major lubricant suppliers - ExxonMobil, ConocoPhillips, Chevron, and , of course Shell, have major financial committments to GTL projects in the middle east.

And no doubt, based on the GTL footprint for GF-5 in 2010, the additive companies are already developing tecnologies for use with the GTL Grp III basestocks.

So, I think EOP basestocks, and any special additive technology, as an alternative to PAO, were about 5 years too late in the initial launch, as capital funds are now being channeled to GTL.

Do you have to mix 50/50 Syn/Dino?? I just bought some PP 5w-30 from Canadian Tire and was going to mix it with dino Penzoil 5w-20. I wanted to run 80%PP/20% dino in my Hemi. I hope this works with no problems.

You can use any propartions you want.

To dubious effect...

FWIW to the OP,
In my '97 Expedition 4.6L w/127k miles, I'm running 5 qt's Pennzoil Platinum 10w30 & 1 qt. Pennzoil dino 10w30. My Expy's engine seems happy.

 

[blupupher]

I got some of that Home Depot Clearance stuff also.
I am running 3.5 qts Pennzoil Dino 5w-20, 1 qt PP 5w-20, and 1 qt PP 5w-30 in my wifes Grand Caravan right now, and 3 more changes that will be about a 50-50 mix of PP and Dino.
