great oil

Have used it in my hot rod and it is a really good oil. As all synthetics go a little pricy but I believe it is worth the added expense.

Summit RacingSummit Racing Verified Purchase

I purchased this product after I called royal purple and spoke to one of their engineers about which of their products I should use in my truck. The person I spoke to was very knowledgeable of their products and guided me to this oil for my 2003 Dodge Ram Cummins diesel. I was a little hesitant to go to synthetic @ 200,000 miles and not to mention going from 15w-40 to 10w-40 this made sense to me after the engineer explained that the 10w had less viscosity only during cold starts and both grades had the same viscosity during operating temperature. I have only have had this oil in for a few weeks so my review is limited as of now but what I have noticed a big difference in the cold starts with temps now in the low 30's the truck starts like it was just shut down!!! Also the engine sounds much quieter than before with the conventional 15w-40 oil. Also I have already seen a slight increase in fuel mileage. The oil is still clean on the stick after a few weeks of driving so the royal purple filter also seems to be doing its job let me tell you this filter is beefy compared to what I was using the metals used seem to be three times as thick I guess you get what you pay for. So far I'm impressed . As far as the Summit experience goes this was my first purchase through them and it has been a very pleasant one and believe me I'm very critical about packing and shipping time and both exceeded my expectations very well packed and very fast shipping time. since I have also ordered some royal purple for my second vehicle and the summit experience was great the second time as well. So I will definitely be using Summit for my parts needs in the future. It was refreshing to do business with a company that has prompt service and that has an efficient shipping department that pays attention to detail with excellent customer communication to boot. Also good pricing THANK YOU GOOD JOB ...read more
