What are oil test on these?

Duro, go to http://www.bobistheoilguy.com/ and read for yourself the used oil sample results. There are better performing oils out there than the ones you listed.

An Amsoil man? Not hardly. But you can count me in on the Chevron Supreme. I do not sell oil either.

I'm not sure about your understanding the process that yields PAO basestocks. There are no liquid crude feedstocks in the manufacturing process.

ISO/SYN is a process engineered by The Chevron Corporation which is short for isomerization. Depending on how long they "cook" the feedstock determines the basestock. It can produce a Gp II ( Chevron has sold some of its patent right to others and this is where most of the Gp II comes from), Gp II+( this is the bulk of Chevrons production), and the ever famous Gp III basestock that is legally a synthetic. The difference between a Gp II+ and Gp III is the Viscosity Index. Gp III basestock oil will generally equal most PAO basestocks but not all. They are water clear liquids, usually need a small amount of Gp II to bind the additive package, have low temp pump rates, have natural anti-corrosion properties, have good to excellent flashpoints, but won't stay with PAO basestocks for extended oil changes. They are resistant to shear but not as good as a PAO. Gp III's will also require more esters for viscosity stabilation than a PAO. Overall, if you need a good quality oil, Gp III is a good choice. If you have thermal extremes, consider a PAO or ester basestock. Did I say that I tend to ramble?

What's the process that Texaco/Havoline uses, I can't remember the name of it? Isn't that process similiar to the Isosyn process that Chevron uses? Also if I'm not mistaken Chevron and Texaco have joined forces but their oils are still seperate.

I was a Texaco station and now I have switched back to Exxon since Shell got a large portion of Texaco with Chevron getting another part. I can't remember what Chevron will get.. I do know that Shell gasoline does not sell in my part of the country.

I think you are referring to their System 3 Technology. It is the same as ISO/SYN. Texaco and Chevron motor oils are almost but not quite the same nowadays. I expect that some day in the near future, one will go away. If you look on the back of the newer bottles it says Texaco/Chevron. It is sad to see two companies that have had such an impact on the industry just disappear into the sunset. And we call it progress.

durocab, Valvoline does fairly well in UOAs but avoid the price leader All Climate. Castrol GTX also performs good. Exxon Uniflow is a good sleeper oil as we don't see very many UAO's on it but those we have seen have been good. Another bargain oil for some of you will be the Mystic JT-8. It turns in some great numbers and I have been told that it is available for cheap at Tractor Supply. I don't have a Tractor Supply anywheres near me so that is second hand info. Other good oils are Delo 400, Rotella-t, Delvac, newer production Pennzoil, Citgo, and Phillips 66 Trop-artic.

Trapper, I think you said your boss had purchased a Titan and if so how's he liking it and what do co-workers think of it after a couple weeks?

Also, I forgot...Are you considering one in the near future since your Ford is relatively a new vehicle? Forgive me if I got you mixed up with someone else.

[Trapper L]

Yepper, the boss has one. You know what boss spells backwards- right? Well, the double s o _ won't let anybody even read the owners manual. He put it on the dyno just for grins but that was it.
Yeah, I have an 02 Supercrew. I usually put 60-70,000 miles on a truck and move it so this March it will need to go.I drive 120-150 miles a day so it doesn't take long. And since I don't fly, any conventions/ corporate meetings means I have to drive like the wind. I haven't totally made up my mind on the options I want yet but the RF radio and electronic locking axle will be on the list. And the color- don't have a clue, I think I like them all. I wonder if I could afford one of each.....hhhhmmmmmm.

Trapper, I had Grand Jury duty today so I got to drive the Titan (the only good part of the day). I assume you have driven the Titan and if so how do you feel about the power and ride compared to your Ford?

[Trapper L]

The one I drove had the bench with Fosgate and tow package. My SCrew has the 4.6 so there is no comparing the power. The Titan was also quieter than my SCrew and rode better. Handling is much better and overall fit and finish is better. I also drove a new F-150 within 30 minutes of the Titan and there is no comparing the trucks. The Titan is a much better value than the Ford, hands down. Now if Nissan had zero percent financing, maybe I could swing one in each color..........

Getting back to the oil question. Do any of you guys know the quality of the factory oil? Based on previous statements of possible cam bering wear on Jets oil tests... wondering if the factory oil is sufficient?

[JetTech]

Trapper, the single most important question I forgot to ask you is what oil do you run in your personal vehicles? And also taking into consideration Nissans recommendations for mineral oil in the viscosities of 5 to 40 depending on temp. what oil and viscosity would you recommend for me living in Atlanta, running the piss out of my truck most of the time? I'm looking for longevity over gas mileage and also want an oil that is very shear stable. My first guess would be Chevron 10W-30 year round. What do you suggest?

I had made up my mind to just use Chevron Supreme but I doubt I'll be able to. Some habits I just can't quit. The Delvac is a gas and diesel oil and has a rock solid additive package along with rock solid used oil analysis in pretty much anything it's put in. I'll do an oil sample on it just to make sure after I put it in. I get fickle when it comes to different oils every now and then

looks like a great oil, OK for gas engines though ??

[JetTech]

yes, it's SL rated for cars.

I will say this though, after listening to Trappers take on the way dino oils stay on the cam chains after shutdown better than synthetics I may just have to change my mind on the whole synthetic oil use. I still may try the Delvac 1 5W-40 BUT will do oil samples along the way to make sure I'm not wearing out my cam bearings or doing any harm by using it. My main concern with dino oils is shearing, something that most synthetics don't do over time. Especially Mobil's Delvac.
