Dixie, I use Super tech as well. Manufactured by Warren Petroleum, or was last time I looked.

It is also what I use for transmission fluid changes. I usually do 3 months because of the consistent short trips I make and idling for extended time. Everything gets a Motorcraft filters. I have actually just tried Pennzoil platinum in the 2000 5.4 Expedition. Will keep an eye on the mileage as it is considered the best as available Synthetic, with the highest detergent and anti-wear package.

 

Awesome. Wouldn't be surprised if they changes suppliers, it's all good though. You don't hardly ever see anyone arguing over what brand of grease they pack their wheel bearings with, but they are made by different petroleum companies as well and I'm pretty sure I have a tube of Warren grease around somewhere. I use whatever works and doesn't harm my equipment.

A little more mileage would be nice but then I think of some of the things I do like off-roading and towing and quickly realize that any gains I might see on the highway or around town would go down the drain anyway.

 

rotella t6 and walmart oil. did get some sale oil from autozone with a puraltor filter, im gonna use to do a flush on a escort im swapping a head on.

motorcraft filters prefered

 

My old school (289).....QS 5-30
My 97 4.6.....QS 5-30 (that's what we started with otherwise I would have used the MC 0-20)
My 06 5.4.....MC 0-20

Tranny's.......auto or stick that requires ATF...Valvoline ATF

 

When I worked in a dealership, we had Mobil 1 on tap. So that's what I started with. Then I changed the oil in the car of the guy that owned the oil company that delivered the oil to the shop, and he would not let us use the bulk oil. Said the requirements on purity on bulk oil was lower than on bottled oil. So he always brought Mobil 1 bottled oil with him.

After thinking about how long the bulk oil tank sat out behind our shop, I started wondering how many contaminants were sinking to the bottom, and when it was getting filled or emptied. That made me switch to always making sure I use bottled oil. I still run Mobil 1 or Rotella on older engines, as that is what we ran in our diesels, and I got the chance to look at the inside of a few engines that were on conventional and synthetic.

The worst engine to look at was the one that didn't ever get it's oil changed. when the drain came out, but the oil was sludge. The write up was 'engine is noisy'. Ended up not being a warranty fix, that made the owner livid!

 

I understand what you are saying, especially the last few inches but, remember the suction inlet is located within 6 inches of the bottom.....so the last few inches where the contaminents are resting, it would be real difficult for those to get "sucked up".

 

I use Shell Rotella 15-40. I use it in my bikes too, its good stuff. IMHO.

 

Use Pennzoil Ultra Platinum Full Synthetic 5W30 in all my vehicles, Mobil 1 filters

 

I use Rotella 15-40 in my 94 460 truck, and change it often. It has a lot of detergents in it, being a diesel oil. Helps keep things clean, especially when coupled with a good oil filter. I normally buy a Mobil-1 oil filter, K&N oil filter, or a Napa Gold series filter.

Fram filters are garbage. Very cheap internal components, and very little filter material.

Here's a link to a really good oil filter thread if anyone cares to read up.

The Anatomy of an Oil Filter: Part 1 ......... - Yellow Bullet Forums

 

Penrite hpr gas (lpg) full mineral oil 20w/60 bit thick,need for the old 302,487600 kms,just gotta hang in for another month or two then new 351 goes in.

 

Thanks for the link. A while back a guy on on of the motorcycle forums I frequent did a similar test and found the Wix filters to be one of the best too.

What is your least favorite oil and why?

 

Anything that doesn't meet current API specs, like non-detergent oil still sold at auto parts stores, and garbage, no-name-brand oils that are typically sold at convenience stores such as this: Petroleum Quality Institute of America - Data Template

Why? Because they're terrible oils that do not perform as well as an oil that does meet current specs, and they will turn to sludge over the course of a normal oil change interval and WILL cause increased wear and could possibly ruin your engine. Also, these companies are run by scumbags, because they know their products are inferior and will damage people's engines, they know that most consumers don't know what API specs are and that the consumers will think this garbage is perfectly fine to use in their cars when they are unknowingly ruining their engines.

Like I said before, I'm not brand loyal and will use just about any oil, but you couldn't pay me to use garbage like this in my vehicles. As long as it meets current API specs, it's a "good" oil, and I'll use it.
