    P0420 code after Protect and Restore

    Why would you use a 0w-20 in these known oil burners. These engines do great with 0w-40. Look into a flush followed by HPL EC or Rislone for a few OCIs.

    HPL EC usage

    Since when did the number of days become a thing with EC? My understanding if you use it a 20% ratio of is safe. It needs heat to do its thing. Also the mileage run recommendation for a few miles is a liability thing as HPL has no idea what condition every engine is in. Hence they will give a...

    Rislone Engine Treatment. How to Use?

    That depends how dirty your engine is. The mileage recommendations are so you do not plug your oil filter up and starve your engine of oil. If you are concerned, run it for 500-1000 miles and change and check your filter. then make your decision. I believe all these cleaners are safe to run...

    3,000 Mile Oil Change

    Oil is relatively cheap engines are expensive. Penny wise pound foolish, for those who say shorter OCIs are a money flush. These same people will then spend many hours messing with piston soaks, UOAs, etc.... I change oil at shorter intervals and use flushes or engine cleaner because I like...

    Couple of J35 questions

    I have own both paste and maintain both for friends and family. What I like is the consistency. Whether is the J35 or J37 a valve adjustment is the same. The timingbelt kits are the same. I have installed many Aisin kits TKH-002 and like them. Sway bar end links are the first to go. When you...

    Valvoline Restore & Protect

    Why are people complaining about the 4 OCIs it takes. Even HPL EC or HPL PCMOs makes no claims of 100% cleaning in 1 OCI. Neither does Rislone and from my experience they both work. What happened to the Anti Engine flush slow cleaning is the way to go guys? I think Valvolines claims are...

    We Bought a 2024 Odyssey

    Congrats may it serve you well! Aleays pleased to see people embracing children. Having owned a few of these since new and running them to well over 200K miles. Good choice on the 5w-30, I ran 5w-30 or thicker and on occasion in the winter might run a 0w-20. None of then ever used oil. I...

    Bobcat t740 hydraulic oil...

    Bobcat specs their "own oil" even for machines not made by them. Generally though many,around here use Delvac Tractor Fluid(Mobil424) or equivalent type fluids in their Bobcat branded equipment. They have some zinc in them.

    Cleaning experiment

    I put HPL EC in the vehicle now, which should be theoretically fairly clean, and see if HPL EC does additional cleaning the the Rislone missed.

    Cleaning experiment

    Update: Just changed oil with slightly under 3K miles. 2934 Cut the filter open and there were also carbonaceous deposits, though I would say bit quite the same amount as the HPL. It appears the Rislone also does some cleaning. Although the deposits felt grittier than with the HPL which would...

    Did piston soak increase my oil consumption?

    Why waste resources, buy 2 QTS of total 10w-60, that should increase the viscosity of your 5w-30 and you can run your "fine" oil until the next OCI. At next OCI use 5w-40.

    Toyota Lexus corroded battery terminal

    I had the same problems, cleaned the terminal, put the pads like Trav mentioned and sprayed with the battery terminal spray. Corrosion never came back.

    Acura Oil Consumption

    having experienced this myself. I have pretty much eliminated the oil consumption on a 3.7L Acura. (Still working on cleaning the varnish). I was consuming 1qt every 1200-1500 YMMV but what I did 1.)PCV was clogged, changed that still burning 2.)Run HPL EC for 2000 miles, improved slightly but...

    High Performance Lubricants Engine Cleaner

    I believe HPL mentioned somewhere that to be technically correct, EC works best with conventional/semi synthetics. It is of course 100% compatible with synthetics but there is a slight advantage to using EC with conventional. This is BITOG after all, so every advantage counts.

    High Performance Lubricants Engine Cleaner

    I believe PCMO cleans better when used full strength because it has ANs as well. EC is concentrated. The way I see it, 1qt EC diluted to 20% would clean better the PCMO diluted to 20%. PCMO at 100% would clean better than EC at 20%. I would not run EC 100%.
