  • Great Oil
Style: 15W40 Full Synthetic Size: 1 Gallon
This is usually my go to oil. If you have the oil kits that take a small amount of oil and filters it to a lower micron, then it might be worth going with blue diamond, however I have the stock setup so I go with this. After months of hard hauling and off-road I drained out the oil and checked it, there’s a simple test you can do to see if the oil was still good, and after 14,000 miles the oil still appeared to have its additive package mostly intact and viscosity seemed like it hadn’t changed. It’s hard to tell without doing an actual oil analysis in a lab so don’t take my word for it. Keep in mind it’s a gallon, so you may need to buy more containers the. You would from other brands that are 5 quarts, but it’s good to have left over oil incase you need to top off. I feel like my engine runs better in this than Valvoline but that is just subjective and there no way for me to prove that at this time. Customer Service from hotshot is also very helpful if and when you give them a call. ... show more

  • Its synthetic oil
Style: 15W40 Full Synthetic Size: 1 Gallon
I have tried a few different types of oil in my 2017 Cummins 6.7 over the years. My RAM is still emissions compliant (unfortunately). I have tried Rotella T6, RP, Amsoil, Valvoline, Regular dealership conventional, and now this stuff. I did not send my oil out for a test before I switched to HSS. I am only going off my driving experience and what it sounds like. After I did the drain and fill and started it up it sounded just about the same as the Amsoil I drained out. It did hold a higher Oil pressure though, but that could also be because the Amsoil had 15k miles and was a year old. But after a couple of hot cycles, it does seem to idle a bit quieter. Fuel mileage remained the same (but I wasn't expecting it to change). One thing I read online is that because they run an additive packet with high....Zink, I believe, it ruins catalytic converters. I am secretly hoping that is true, because I have what I need to "fix" that problem. The smell of the emissions exhaust now is much more pungent and annoying now, so the claim of having more additive of some kind is likely true. Still runs about the same temp (199-210F) when driving empty or towing. Overall, for the price, I will probably go with it again, or Rotella T6 (my engine seems to like either of those with an RP filter) ... show more

  • Actual shocking how good it works
Style: 15W40 Full Synthetic Size: 1 Gallon
Legit stuff right here. Literally can’t believe how different it made my lly run. Actually feels like I gained a lot of horsepower running it. Very smooth and overall quality oil. Worth the extra few bucks. At least every once and awhile

  • Only oil I use
Style: 15W40 Full Synthetic Size: 1 Gallon
I have a 2002 Silverado 2500HD with about 395k miles on her. I have used a number of different brands of oil over the years. For the past two years, this has been the only oil I use. I do a lot of towing, and often have extended oil changes. It performs just as well as when I put it in. The first time using this, the engine ran much quieter. I can't say much for the mileage claims as I often have varying loads that offer different mileage. The claims that this oil stands up to the abuse are actually true. ... show more
