HPL fully formulated oil has higher cleaning abilities than the HPL EC. HPL EC is to VERY GENTLY begin the cleaning before going to the fully formulated HPL oils.For example, would there be any point to adding the HPL EC to HPL fully formulated oil?
I used to mix oils fairly often, until I realized that using a high-quality Fully Formulated Oil is more important than any of my under-educated guesses. Looking at the VOA's of many oils, there are more than a couple of ways to make a good-performing end product. I simply don't know enough to make guesses with the chemistries by mixing my own.
As I mentioned earlier you got me thinking. This product is now on the top of my list of engine cleaning products if I had a need for one. For friends or family looking for a recommendation I'd suggest giving this a try, straight out of the jug, no mixing with anything.
In fact I might throw it in the 08 Liberty for the winter OCI. With the change of my wife's driving pattern I switched to 6 month OCIs and I will be changing the oil late fall.
Makes sense.
All the oil in the system is pumped over and over through the oil filter, so anything suspended will be filtered. Only "big chunks" that break off might get caught in random pockets in the heads for instance, and might not ever get sent to the filter. But Valvoline R&P isn't suppose to be that aggressive, and is suppose to slowly desolve deposits. If "chunks" get caught someplace, maybe they would be slowly desolved away with further cleaning.
I'm running this combo in my Rodeo as we speak & am around the 3k mile mark. If you search my posts on the matter, I share the response I got from David from HPL before I decided to try it out. In a nutshell, I started running their regular pcmo in a heavily varnished engine, & wondered if it would be safe to top off with a qt of their ec40 & boost the cleaning efficiency. The answer was yes it is safe, & does increase the cleaning capabilities of the pcmo, albeit at a higher cost than just using one of their more premium oils alone.For example, would there be any point to adding the HPL EC to HPL fully formulated oil?
A very supportive review for the Valvoline Restore and Protect from a long time trusted BITOG member. Thanks.
exactly the recipe my K24 just got
Wouldn't the only way to confirm would be to perform UOA? Engine, climate and driving habits all impact the degradation of the oil.I must say that I'm very impressed with the quick response from Valvoline to their emails! Most emails to oil companies go completely unanswered or take weeks to respond, but I sent an email about an hour ago and already got a response, even though it's quite early in the morning in North America. The only thing is that they really didn't answer my questions to my satisfaction
My first question was when R&P was coming to Canada and they didn't have a time frame for that. My second question was whether this oil is formulated to handle 10,000 mile intervals and they just gave the typical response "We stand behind and recommend you follow the OEM service intervals for your vehicle"
I do think that once my engine is cleaned up, that this oil should be ok for me to run 10,000 mile intervals in my Civic like I've been doing with many other oils. My plan is to run the first interval at 6k, and then if I do decide to keep using it, the second interval would be 7500, and then follow the oil life monitor from then on, which is typically 10k.
For sure, but I was basically asking them if this oil is formulated like a longer drain oil (such as their own Extended Protection oil)
If you have a engine with a worn out seal that may be seeping oil and then go in with any oil that is designed to clean more compared to others including using flush products you could clean up sludge/carbon build up that was preventing that seal from fully leaking.
