Can anyone help me comparing Mobile 1 synthetic oil to Penzoil synthetic oil.

Both companies should have product data sheets avaliable on their respective websites. These sheets will list parameters such as 100C and 40C viscosities, flash point, pour point, cold cranking viscosity, viscosity index, etc. This should give you a good basis for an initial comparison. Be sure you get product data sheets (may vary in exact name), not material safety data sheets (MSDS).

Unless they've added this info to their site, this tech. data is not availabe on the Mobil site; you might be able to obtain it by calling them ?

Mobil is a pao based formulation while the Pennzoil is a group III based oil .

Although some of the group III formulations offer very good performance for the same money I pick the pao and Mobil has a very , very good additive package .

Please try the Pennzoil and have it tested after using in your car and let us know the results .

Winston. Do you know the type of synthetic in other brands? Particularly I am interested in Valvoline Synpower.

I am using Valvoline Maxlife which I understand (from much discussion at the oil guy forum) is a group II with about 10% or so ester synthetics. Would that be a good one to "juice up" with some PAO? I could add Mobil 1, but would prefer to stay in brand. My thinking is mainly to improve cold startability, but maybe this mix would be good year round.

AMSOIL has run a number of bench tests comparing various oils, all 10W-30. These include the ones you are interested in.
You can find this at amsoil.com.

This should tell you all there is to know about Mobil 1. Wouldn't use anything else. It is simply the best on the market.

You can find a comparison here

Thanks fred, you beat me to the punch. Amsoil is the hands down winner in a comparison with Mobil 1. PERIOD!

I've used Mobile 1 synthetic oil,Penzoil synthetic oil, and all Amsoil products. To continue, I have used the Havs, Vavs, and Quakers, but I have yet to find one oil that compares to Convoy (Conklin) parasynthetics. I have saved money from cold weather start-ups, and as gas is $1.60 at the pupmps, I do NOT see how anyone can afford NOT to use Convoy. The problem with other products is that they break down much more quicker than Convoy. Is it just me, but are you not suppose to increase horsepower also when using these expensive oils? Convoy gives me better gas efficiency AND increased horsepower. For those gas hog drivers and those HP crazed fans, CONVOY is the way to go.

Just Curious

Do most companies in the business of selling oil give their customers a guarantee that their products will perform as intended and if not, a 100% money back? Conklin products have help me for the past 4 years from Convoy (cold weather start-ups; engine cooling because I run one of my company vehicles without antifreeze all year long and I have had no trouble out of it as I put 25k on it the past 3 years) to Fuel Mate fuel conditioners to save me money at the pump. It seems Conklin products are great and proven, but Many people I speak with are reluctant to use the 30 year old products....Are there any reasons from you all as to why this is?

Extremely Apodicitic, do you have any oil analysis done with Conklin? Talk is just that, back it up with hard facts and evidence.

I'd be interested in seeing those test results too. I know these oils have been around for a long time but would like to see some test results related data. Thanks.

Just based on Conklin's web site, their oil looks like a pretty poor value:

http://www.conklin.com/divisions/files/Lubes_catalog03.pdf

The compare their 10W30 to Mobil, Valvoline, etc, synthetic blends, and it comes out just barely better, but doesn't the Conklin cost something like $7/qt? So, Conklin looks to be a amsoil and redline priced oil that is out performed by $4-$5 /qt Mobil 1, Delvac 1, or German castrol. I suspect that some Group III synthetics like Rotella 5W40 perform better as well, and for $3/qt.


To go even further, based on Conklin's spec sheet compares their 15W40's pout point to Rotella T, which is well known to have the worst cold flow properties of any of th common 15W40's. Delvac 1300 has the same pourpoint as Conklin, and costs less than $2/qt:

Conklin's marketing tactics seem a little shady too: they seem to rely on a combination of dubious personal testimonies, and Amway style marketing to make up for a lack of actual product value.

I know that Conklin is or was made by Amway. They may have shrouded the relationship because Amway has such a horrible reputation.

hey, have u guys realized a new technology synthetic oil not using PAOs and others..Theyre using calcium carbonate additives within petroleum sulfonate base oils.. try checking dmxtechcorp. youll be surprised bec the oil is good.

cranston

I've been in the lubricants business since 1979. I've sold and used just about every brand available. After my years of research, I'm now convinced that AMSOIL is the superior product line. My 1998 Ford E-350 has right at 415,000 miles on it, changing oil every 20,000 miles and oil filters ever 10,000. The savings in oil changes alone is enough to purchase a new van, and I might add, I don't need to.

This one should work. Sorry bout that.

@ CharlieB: impressive salestalk!

The Amsoil comparison is interesting, but has any company published a comparison of their products with others and not been in first place?

And that 4-ball wear test? I can't get the 4-ball numbers on other products products by those other makers. Do they all avoid the 4-ball test because their oils are terrible flops when it comes to performance and this test would prove that? I'll bet that Mobil is terrified when someone brings up their poor performance in the 4-ball wear test as done by Amsoil. I guess that's why they blast the market with all these new labels hoping that you will forget the 4-ball test. I guess it shows, Amsoil has more balls than the competition and Al is just the guy to lead the charge.
