Can I go wrong wth Pennzoil?

[FastSUV]

History: I have been die-hard Castrol dino fan in my past; Mobil 1 fan for synthetic. These are not all the vehicles I have owned, but are only ones with a good metric established.

Castrol GTX 10w30 0-149k, 4-7k OCI - '89 Nissan p/u 4cyl SOLD...used some oil

Castrol GTX 10w30 118k-150k 3k OCI, then 150k-181k Castrol GTX HM 10w40, 3k OCI - '92 Camaro 5.0L SOLD... used some oil, needed valve stem seals

Mobil 1 10w30 66k-150k, 3k OCI, then 150k-178k Mobil 1 10w30 HM, 3-4k OCI - '98 Jeep 5.9L CURRENT...uses some oil, minor leaks

Castrol GTX 10w30 65k-69k, 4k OCI, then 69k-73k Trop-Artic 10w30 syn-blend, 4k OCI - '01 Jeep 4.0L CURRENT...uses very little oil, minor leaks

After reading this board (& based on my preferred OCI), I am convinced that the best choices for the money are Pennzoil 10w30 YB for the 4.0L, and Pennzoil High Mileage dino for the 5.9L...

Also, for a synthetic (for any future cars I may want to run it in), that Pennzoil Platinum 10w30 is the best choice/value.

Based on all of your data & UOA that you guys have read & accumulated in your tenure, can I go wrong with switching to Pennzoil products accross the board???

OR...should I stick to Trop-Artic & Castrol for the dino/blend variety of oil since I am deciding not to use Mobil 1 or other synthetics for now?

Nope... Good stuff IMO.

I would use a 5w30 instead of the 10w30 because they are virtually the same but have a bit better flow characteristics and may come in handy if you experience Winter in your area of the US.

Well in Oklahoma we see 0*-110* but avg winter is 20*-40* & summer 85*-100*

I would use 5w30 all year or just in the winter, and 10w30 only in the summer...

If Castrol has been working for you, why switch? Pennzoil isn't my first choice but I'd use it if I had to.

From what eveyone tells me...pick a bottle based on color and you won't make a wrong choice when it comes to SM oils. If you like yellow, pick Pennzoil. If you like white red and green, pick GTX. White w/Blue and red, Valvoline (most American)
Green, QS...etc..

Well which is better between Pennzoil High Mileage Conventional & Castrol High Mileage???

I have heard that no matter what Pennzoil oil you choose, many have reported better MPG with it over Castrol, Valvoline, etc...

I prefer the Pennzoil. They are both good oils.

It would be very difficult to quantify any MPG gain or loss simply by switching oils. The butt dyno is not a legitimate piece of testing equipment.

 

[Johnny]

Well, it might not be in WA, but it is in OK, TX, and WI.

 

[jldcol]

Can you go wrong with Pennzoil? technically yes, if you expect to much of it. The same goes for any oil really. Will it replace bearing metal? no, will it double your mpg's? no. Will it changed regularly allow your vehicle to function long, long after you are sick of it? yea.

My girlfriend thinks it is

 

[jldcol]

Yea ok, but is that her's or yours?

 

[jldcol]

One other thing, is that banana doing what I think it's doing? and 2 handed, thats some skill set.

 

[jldcol]

One more for the trifecta, if it's hers tell her you need to calibrate her using other dyno's as comparisons. Bring this up with her, it should go well provided your medical insurance is paid up.

 

[webfors]

Can't go wrong with any SM oil, especially PZ. Fill her up and enjoy

 

[Bambam]

Use recommended grade and any and all will serve you fine.

 

[greg_J35]

No,you can't go wrong with Pennzoil.

 

[Badlees]

You just can't beat the price of Pennzoil conventional. I can't find Motorcraft 5w30 at Walmart in the big jugs so Pennzoil is the choice. For some reason Valvoline is $2.00 more than the YB at my Walmart.
