I have never done oil analysis before. I received 6 free oil analysis kits with my recent oil purchase from my distributor. How should does one get started doing this? I have over a dozen pieces of diesel equipment ranging from pickups, to tractors, to crawlers, backhoes, UTVs, skid steers...

Thanks for the replies. I asked and they had no info. I am sure someone in the company does but the person I spoke to did not. A google search did not bring up much. The oil is not for customers it is for myself. I have a small business and have over a dozen things with Diesel engines. We have...

Is anyone familiar with this oil? Western Marketing is a huge oil distributor in our area and this is their house brand. I buy my oil in 55 gal drums and I can get a drum of this 5w40 synthetic cheaper than I am paying for name brand 15w40. I can't find any info on it. Western Marketing...

Since engines are liquid cooled and have a set operating temperature why does the upper ambient temperature matter when selecting an oil grade? I totally get the low ambient temp being important because the oil has to be able to flow at startup in a cold engine but the engine gets to 200+...

I have many things with engines and some don't get used very often. The old adage is 3 months or 3000 miles and we all know that 3000 miles is most likely too soon with modern oils. So how often should I change oil if I don't hit my mileage threshold in a reasonable time? I have a pickup that...

Thanks for the lengthy reply dnewton. What you outline is exactly what I was getting at. Their severe service criteria makes no sense. It does make one wonder though why they include it or why they don't just spec 5w40 for everything since most people do at least one of the items on their list...

The manual states to use 10W30 unless it is severe service then they recommend 5W40. 15W40 is listed as suitable for temps above 20F for normal service. They classify severe service as: 1)frequent idling 2)low speed use 3)sustained temps below 10 F 4)operating in severe dust conditions...

Lots of folks recommending the T5 10w30 synthetic blend. I have never used a "blend" oil before. Always kind of seemed like a gimmick to me. Either use synthetic or not. Maybe I was wrong and it is good?

What constitutes cold? I live in the Texas panhandle. I also travel to oklahoma and Kansas. It is really rare for me to see below zero but single digits are not uncommon. Some people are recommending a 10w30 as a one size fits all. Why this instead of 5w30? Most my gas engines spec a 5w oil...

That way you only have to stock two oils. I would be hesitant to run a 5W30 in Texas summer heat in a diesel...

I currently own 11 things with diesel engines (light trucks, heavy trucks, tractors, skid steers, generators, compressors, etc) and 10 things with gas engines like cars, pickups, atvs, utvs and then about 5 small gas engines like lawn mowers, pressure washers, generators, etc. As you can...
