When I worked there a couple years ago, our oil was from Coastal. I don't know who actually manufactured the oil or its quality though. All I can say is I used it several times with good results, and we sold a lot of it.

jldcol, that is perfectly consistent with my type of OCD. Not only do I want to know how something behaves, but why it behaves that way as well. That is an excellent explanation that I have not heard. Additionally, it makes perfect sense. The owners manual says it is normal to have to add up to...

You know Steve S, that's exactly what my father (ASE certified mechanic with over 30 years experience) told me, but my OCD nature was still concerned as none of my vehicles have ever used any oil. Having one that does (or may) just concerned me a little, but the more I read, its either normal or...

You know jldcol, I had not thought of that, but I don't know why. When I was working on my undergraduate degree, I worked at an auto supply, and we had people do that all the time. That is definitely a viable option for me. I really much prefer changing my own oil simply for my peace of mind...

I definitely do not have a rear main seal leak. The usage strikes me as funny though because when I was changing my own oil I never noticed any usage. Now I take it to the dealership as my apartment won't allow us to work on vehicles in the parking lot. Each time I get the receipt from the...

Ok guys, heres what I have. Its a 2000 F-150 4X2 with the 4.2 L V-6 with about 125k miles. I drive it about 32 miles round trip to school 5 days a week. I have been running the Motorcraft 5w20 and changing it at 5k, but have noticed that between oil changes I use about 3/4-1 qt. Is this amount...

Our lab has 3 NMR's, but the tech who runs the lab is out of town for the next two weeks, so I was trying to do some preliminary work. We are working on another way to detect aromatics, and I wanted to see if it was also useful for quantitation if I could find published numbers for the...

Hello everyone. I am working on a school project where we are analyzing some oils for aromatic content, and we are comparing them to some well known engine oils. The problem is, I cannot find published numbers anywhere for the total aromatic content of any of these oils. I e-mailed Castrol, but...

Maybe someone could clear this up for me. I was under the impression that if the climate conditions were suitable, 10w30 would be a better choice because it would contain less VII's to cover the range than a 5w30. Ultimately, this should mean a 10w30 would be more shear stable than a 5w30...

We'll a trip to the parts store myde my decision for me. I was intent on buying Castrol GTX 10W30, but while browsing I found Motorcraft 10W30 on the shelf. It was cheaper and a semi-synthetic which can't hurt right? I figure with the average weather down here and the miles on my truck I am...

Thanks to everyone for the replies and recommendations.

Hey everyone. First, I want to tell everyone thanks for the great information in this forum. I have learned so much. I know there is still a ton of information out there. Here is the question. I have a 1992 Ford Ranger with a 2.3l four cylinder. It has 132,000 miles on in right now. For years I...
