Folks don't need documentation to have an opinion. That's the difference between a fact and an opinion. A fact is documented, an opinion is not. Much of the comunication we have here is opinion. When people offer up a fact it can be documented. But we don't hound people who don't provide documentation or gloat about it.

 

If the UOA numbers keep coming in as solid as is claimed, then Pennzoil's reputation as a motor oil will continue to improve. The numbers will do the talking.

Also, to nit-pick just a little, regarding documentation, I wouldn't have minded seeing a couple of links to those Pennzoil UOAs over at BITOG that are being alluded to (I can be a little lazy on Sunday mornings sometimes...)

 

So I need to have oil tests to prove it didn't work as well? I don't think so. I'm not a Penzoil basher, I just know from FIRST HAND EXPERIENCE that it didn't work well enough for me to continue using it. I'm not talking about their gas engine oils, just the 15W40 for diesels. If my oil is foaming, that's not an opinion, it's a fact! Same for the engine running louder. I don't need an oil analysis to tell me that the engine is running louder and rougher. That's a fact, not an opinion. I don't know why you're being so stubborn when I posted what you asked for, legimitate reasons that I stopped using Penzoil. Rather than you calling someone like myself a "Penzoil basher" I think the truth is that you are a "Penzoil cult-member." Regardless of facts and opinions, you will deny any truth to them and refuse to budge your opinion.

Provide some facts that aren't from Penzoil that their diesel oil is better than Rotella or Delo.

 

DUDE'S,DUDE'S,can't we all just get along The truth is the reason I started to use Pennzoil was from a old show of shade tree mech.,they were talking about new motor oil's for newer car's and they said that Pennzoil was at that time ahead of the game on motor oil,so I tried it,and liked it,and as I have said sooo many time's it's slicker,and that mean's less friction,no matter how you cut it. I also might use Rottela in a diesel if I had one,it's a little kin to Pennzoil now.

 

How did you know your oil was foaming? Just humor me here. Air bubbles on your dipstick does NOT indicate foaming. 99% of the time if foaming does occur it is because the engine was over filled with oil. Foaming has NOTHING to do with the brand of oil used. It has to do with air becoming introduced to the oil. That is caused by overfilling or mechanical problems and not the oil being used.

I would also think if your engine is that sensitive to oil (i don't think this is the case) that you have an engine problem and not a oil problem.

As for UOA go to bobistheoilguy.com and go to the UOA forums. Not that hard.

I am not a cult member of anything friends. I don't even use pennzoil anymore. I switched years ago to cheaper brands just because I feel at the 3K mile intervals that I use the brand means nothing so I choose my oils on price. I contend that the bashing is from prejudice and not facts and the UOA on pennzoil shows it is the cream of the crop.

johndiesel, You "saying" your oil is foaming is NOT a fact. It is a comment. Just to be fair I am still asking for facts which have never shown up in these threads. As horsepuller said what you state is a opinion and NOT a fact.

Horsepuller I am not starting a fight here but I think I have the right to ask for proof if comments are given as facts.

 

I have provided my facts just go the the website that I have posted and look for yourself.

I also NEVER asked for "legimitate" (your spelling) reasons. I asked for facts or proof and not one single person has ever had either in these Pennzoil topics.

 

FACT: A couple of times it caused the check engine light to come on and the injection system shut down. I know how much oil my engine takes (14 quarts) and it was in the correct range on the dipstick. After taking it in for service the oil was determined to be foaming, which will shut down the injection system to protect the engine. After switching oils I haven't had this problem again.

Give me a break on the spelling, we all make a slip on the keyboard now and again.

 

Oh well ,i've used Castrol oil now for over 36 + years and i sleep good, maybe here in CA.penn is blended different ? even the Ford dealership i worked for 20 years dropped penn. oil ,and started to uses castrol & motorcraft oil, reson after pulling apart engines that had used penn. and finding all crud and sludge ,they changed over. But maybe here in CA. it's made different?

 

I also use Castrol in my gasoline vehicles, and Shell Rotella in my diesel. I WILL NOT use Pennzoil, or Quaker State in my vehicles (or lawn mower)!!

 

Bob Ayers , thats ture i dont us it in my mower too.

 

I've been driving and maintaining my own vehicles since 1971 and I always bought what was on sale when I had to change oil as long as it was a name brand oil. That would include Pennzoil, Castrol, Quaker State, Kendall, Mobil, Exxon, Shell, Havoline and Sunoco and never an engine problem. Same for filters. As long as maintenence is performed in a timely manner with good quality products, you won't have a problem with the engine.

 

i have used pennzoil for years and never had any troubles, i always change at 3,000 miles. the only motor i dont use it in is the lawnmower and i run mobil 1 20/50 synthetic in it. i use pennzoil for the same reasons some guys use their favorite oil-its what dad used. i run the synthetic in the mower because i only change it once a year, when it sees use it runs hot (briggs ^ stratton vertcal shaft 3.5 hp) and at full throttle. (plus i modified the tension on the governor spring so i can override the govenor in heavy grass if needed) bottom line, if you maintain your equipment ,brand choice makes little difference. (in my opinion, of course)

 

Frank D,I'll go along with that ,but what racsan said is the Key ( " ever 3,000 miles " )

 

I don't adhere to the 3000 mile idea. I think it depends on the area you live in and your driving conditions. When I lived in NYC I would put 10,000 miles a year on my car and change the oil every 3 months and the oil always came out black as coal. And with the air filter, I would change it once a year and it would always be clogged with dirt from NYC's polluted air and lots of stop and go driving. Now that I live in upstate NY away from NYC's dirty air I put 30,000 miles a year on my vehicle and I change the oil every 5000 miles and it is barely brown. I replace the air filter yearly and it barely has any dirt on it. Hardly any stop and go driving any more. My feeling is that you have to consider a lot of factors in determining your OCI and picking a number like 3000 miles isn't always the proper number. Part of losing our dependence on foreign oil has to start with smarter thinking on our part, just my humble opinion.

 

Yes ,when i put my lube sticker on my ride it will have 3,000 miles or 3 months.
