Thats all fine and dandy. I'm glad you have had good luck with HPL. Im sorry you have had so many doctors in your life to praise and stay away from. I'm not sure how to relate doctors to engine oil.Sponsor or not. Praise goes to people, businesses etc that earn it. I just dabble in my oil changes and have tried many things from many recommendations for cleaning etc. over the years. Some worked some didn't and I passed that on the same way.
The results I saw in my own vehicles from HPL EC30 led me to want to try more. The others users who had a lot of interaction and response from HPL and their service is phenomenal. I reached out to Dave with some geared to my use/concerns and he responded very quickly. One member even posted that he was told by them NOT to use their oil as it would be waste of their money for what they were looking for from it.
Old friend (RIP) was BMW mechanic. He told me to try some BG Synchro Shift II in my Corolla MT tranny. 3 shops said I needed a rebuild after many fluid changes. BG fixed my issue and drove another 100k with perfect shifts until it got totaled. Same scenario for their BG 44k vs Techron for me. I also had some BG concerns when Toyota used something I didn't ask for. BG tech support confirmed my concerns and sent email with details. Toyota dealer did 3 more tranny D&F after that. I respect and will use BG products.
I praised many doctors I had experience with and said stay away from others. Those doctors earned their respective reputations.
The VRP seems to be a really good alternative so far to help many get and stay clean for no extra money vs other quality oils. When my stash of other stuff runs out I will probably try and then cut filters to see my own experience.
Mobil 1 is great as well as others. When you have vehicles that have been on steady diets of M1/PP, no extended changes and you always cut filters before with nothing noted. Then you switch to VRP or HPL and find lots of junk in the filters or noticeably reduced oil usage and less start up noise etc. then maybe you will be open for other options. Maybe even praise those products and companies.
VRP is new as of 1-2 months ago. Ive seen this song and dance time and time again on BITOG. The new thing comes out, its a bangwagon. Everybody jumps on. Dave is a good guy. I have met Dave. Dave is in the market to sell oil. I'm glad he is successful.
You seem easily swayed to now jump onto the VRP bandwagon. Im sure its going to solve all of your oil related problems and clean all your dirty engines better than any other oil there is. Have you been finding lots of "junk" in your filters? Maybe its time to shorten your oil change intervals or not jump on the bandwagons?
