quote:The 15W40 has the same pumpability as a 10W? Thats pretty cool, so really its more like a 10W40 than a 15W40 huh? Interesting - I'll do some board hunting.
Originally posted by dragboat: I think it was Jay that did the math and posted the 15/40 blend could be marketed as a 10w if wanted.
quote:My guess, as that is all it would be, is that marketing/common viscosity has a lot to do with it. One thing most don't know or understand is that a single oil can sometimes qualify as a multiple visc oil... example... say this 15w40 obviously qualifies as a 15w, but then they may take the test to see if it can qualify as a 10w and it too can pass the same test for 10w, so now that same oil can be marketed as both 15w and 10w40. In some cases where some of these full synth's are involved such as m1 or maybe amsoil, one oil could be one in the same for say a 10w30,5w30 and a 0w30. It's just that they only need to meet the spec for that viscosity then they could label it as such, retest that same oil and if it meets the lower spec, label it as such. And for the record, I have been running the Schaeffers 7000 blend 15w40 in my 1.9L ford escort and recently switched to the Schaeffers 15w40 moly bond . I'm doing this as an experiment and will be posting results in the near future.
Originally posted by Patman: If it qualifies as a 10w40, then why is it advertised as a 15w40? Is this because 15w40 is such a common viscosity for farmers to use, so it's easier to market it to them? Or is it simply because 10w40 has gotten such a bad rep over the years?
quote:Dominic, I too have Increased mpg and most, but not all of my 300 +- customers see better mpg. My RV went from 7.0 to 8.2-9.00 after changing rear end lube and moly bond x 200 in the engine. Most new cars & trucks will not see an increase but most all older cars & trucks will. Many are from 5% to 10%. Sometimes even more. David Solomon

quote:Well, it's kinda hard to have a good answer for that! I guest it's because that's what I used in my trucks for 10 years and going to 24,000 miles on intervals, and no problems at all. I have many heavy equipment customers and some use moly bond and others use Supreme 7000. The moly bond in (my) opinon does better than the Supreme 7000 in older heavy equip. Why ? I really don't know. I guess that's what I sell more of, to these customers. They may have a few newer pieces of equip. and many older pieces. I just think the moly bond and micron moly are better choices for older and higher hrs/miles on cars trucks and heavy equip. When I go to a new prospect of this type and I see alot of older things setting on the yard, then I just talked about moly bond Just My Opinon
Originally posted by 59 Vetteman: David and Bob, As you know I use the Schaeffer's 15W40 Series 7000 in my new PSD, 15 quarts and second change. My question is this: I notice that you and Bob tend to lean to the Moly Bond over the Semi-Synthetic and I am curious why? Price is not a concern to me on this, so are there other attributes of the Moly Bond over the semi-syn that I am missing?
