I've been using RP HMX for years, but a problem I see recently is their pricing of non-Synerlec API products in the modern era of quality, cheap synthetic oils for GDI engines and whatnot. Being on BITOG really does open the mind lol. The non-Synerlec oils should be no more than $25, if not slightly less. This will help justify the lack of additives that are found in their racing oils. More people will buy it too! BITOG might even celebrate it with a few threads!I absolutely expected some crappy condescending remark like that. The operative word in your response is "here". You have about 15,000 posts, so you are a long time member. You must be willfully ignoring the past 10+ years. RP has been hated with a passion, mostly by ones who have never even used it. NO oil elicits as much scorn as RP. None has ever been bashed as much. I have zero need to "make a technical argument or response" to suit you. Just open your eyes, look back over the past 10 years, and drop your willful ignorance.
I'm only gonna get the Synerlec stuff from now on. I know my engines love their HMX line. They stay clean, and the oil has kept unusual noises to a minimum in our pushrod V8's. Will be trying 10w-40 HPS in the LS1 next! The Toyotas love the 5w-30 HMX.
