I just started ordering coffee online since my area does not carry any good coffee.

For 5 lbs of coffee I pay almost $8 shipping. On a case (25lbs) of Amsoil shipping is $8.25 It's more than reasonable!!!

Why Does AMSOIL Produce XL Synthetic Motor Oil?

Market research told us we needed to have a product with API certification. Therefore, we produced the 7,500-mile/6-month formulation specifically for this program. We want to emphasize that although the recommended
drain intervals are shorter, our product is an excellent synthetic oil. With the exception of the 25,000-mile/one-year drain interval, XL Synthetic Motor Oil still provides all of the same benefits as our premium synthetic motor oil, including
fuel economy, cold temperature fluidity, cooler operating temperature in hot weather, superior wear protection and increased power. Our 25,000-mile/one-year and 35,000-mile/one-year lubricants have higher TBNs, better shear stability, better oxidation protection and a host of other proprietary formulation features that allow the longer drain intervals.

Exactly....compare the specs. of Amsoil 5w20 to Mobil 0W20 and Amsoil starts to look pretty good. I do not know what it has for zinc & phosphorous, but I will bet it has significantly more than the anemic Mobil.

Yeah, Mobil 1 with all that moly and boron (neither of which you will find in Amsoil) is sure anemic.

As for ZDDP, the XL-7500 is API certified, which means the level is capped just as with Mobil 1.

the XL-7500 is a EXCELLENT oil for engines,and meets the maunf. specs,though being a stong group 3 and a balanced add pac,lubrizol,I still am not sure why this oil seens to be picked on,as for a groupe 3 its easy one of the best next to Shell Rotella 5w-40,,though Mobil 1 and a price diff. is close,,,what does it take in dollars to fill your tank of fuel,is the difference there??........BL

G-Man,

Yes Mobil has some moly & boron....if you look at the used oil analysis, you will see that they are a little lean on zinc & phosphorous - maybe Amsoil goes right to the maximum that the cap allows? I am not sure that the moly & boron is helping Mobil any against wear with their 0W20. I think Amsoil 5W20 is a decent oil.

I made a mistake on the pour point for Amsoil - it should read -46C.
