I am just curious, have any of you used Pennzoil Platinum in any of your vehicles and if so how do you like it. I never thought I would ask about any Pennzoil product and I will probably stay with Valvoline but I am just curious.

I can figure out most computer systems but all of the different motor oil gives me a head ace.
I just bought some ford Motorcraft 5W-30 that says synthetic blend on the bottle.
For 40 years it has been just plain old multi grade engine oil.
But Now it is called a SYTHETHIC BLEND.
So I think it is some of lying Bill Ford's stuff.
I am from Missouri so they are going to have to show me.
But It does not look like synthetic to me.

I don't like Pennzoil never have always a Mobil-1 guy,but i have been
hearing good things about PP it's a better oil today than it was years
ago,i would go ahead and use it over the Valvoline for sure plus right
now its buy one get one free at Advanced Auto,,great deal for a full
synthetic oil..try it!!!!!

After talking to several different mechanics at several different places, both dealerships and independant shops, I have decided to stay with Valvoline. I told them that I had a 2006 Sierra with a 6.0L engine and 500 miles on it and asked if it was theirs what would they use and most said Valvoline, a few who worked at the Lincoln dealership said Motorcraft and one said if I wanted the best synthetic to use RedLine.

I had not told them what I used. I asked about Pennzoil and most said they would not use it but it was my engine to use what I wanted except for one that said he would walk before he put any Pennzoil in his engine.

I have never used anything except for Valvoline and never have any trouble, so I guess I will continue to use it.

Just because a guy is a "mechanic",,,doesn't make him a professional on oil's....good luck. :)

That is true!

Nothing but Valvoline in our vehicles.

I have always used pennzoil in my truck for the last 7 years every oil change. I have never ever had one problem .
I am no oil expert , but I say as long as you change your oil when recommened , use what you want.

I agree.. if you like penn. you should head to AA and grab
some of that PP synthetic for buy one get one free..

I used the pennzoil platinum once because the shop was out of mobile 1 and i didn't like it. The motor sounded louder. Now i only use mobil 1!!

Alot of people told me that Mobile 1 got rid of their piston slap problem. Using just dino-oil made the engine sound louder. In my opion I would stay with synthetic because I never had any internal damage done to my lt1 with just over 300K.

I have had this truck for 9 1/2 months now and it turned 3,000 miles today. I have changed the oil for the second time and used Valvoline DuraBlend again. I fugure by the time I trade the truck it might have 9,000 miles on it so I think I will stay with DuraBlend.

Is it a bad for your engine if you switch to semi or full synthetic after 50K or so????

Nope...do it any time now,you'll be just fine.

Shell Rotella T 15W-40. It's a commercial oil far superior than anything off the shelf.

Alot of people told me that Mobile 1 got rid of their piston slap problem. .

Unfortunately Piston slap in my 2k2 was not reduced with Mobil 1; but I do agree my engine seems to run a little quieter with it.

Now with 113K miles on it.

i am for mobile 1 i have used it in my truck since i bought it and i used it in my ls1 trans am and seems to make them run smoother and it stays cleaner alot longer than most oils.
