HPL Cleaner - Drain Interval?

My wife's 2016 Mazda CX-5 with the GDI 2.4L (140k miles) has been consuming more and more oil as time goes on. Probably closer to a quart every 1,000 miles now. She does a lot of short trips, multiple times a day which doesn't help. Aside from the oil consumption, it runs great!

Due to the "severe" nature of all the short trips I usually change the oil every 3k with quality 5W-30 synthetic, never exceeding 5k. Not that it is a very scientific observation but the oil always turns black quick, at 3k miles it looks like ink.

I'm going to do the next couple oil changes with a quart of HPL's EC30 engine cleaner. What would a good oil change interval be? Stick with 3k? Sooner? Later?

I don't expect the HPL cleaner to cure oil consumption but perhaps it will clean the rings up a bit. When it is time for the oil change I am going to do a B12 piston soak too to see if that will help. Thoughts?
 
What kind of OCIs were you running up to 140K? I ask because the Skyactiv (2.5 not 2.4) isn't known to be an oil burner with such relatively low miles (my inlaws 2015 has over 220K and burns less than a quart in 6 or 7K OCIs).

As far as the HPL cleaner ....I'd do 3 or 4K on it and I do like your idea of a B12 piston soak. Good Luck with it.

PS: After reading dnewton3's post I'd probably run the slightly over sized 7317 oil filter during the cleaning phase.
 
If you're adding 1 quart approx. every 1k miles then you've already changed all of the oil in the sump by the time you change the oil at 3k miles. IJS.

HPL EC interval is around 3k miles I believe. The ratio of cleaner to oil is 1:5. Personally I wouldn't bother. I would just try the B12 piston soak first and then monitor.

Have you considered just running their oil? Their oil can clean better.

BTW, do we know if HPL uses POE or diester? I heard some use diester, which I believe is a good cleaning ester.

going straight to their oils on a dirty motor is not advised as it can clean too fast. HPL EC is a more gentle cleaner than their oil to help not overwhelm the filter.
 
Up until about 100k I ran about 5k intervals but my wife didn't run short trips back then. For the past 30k miles or so she has really been short tripping and I've been trying to keep the intervals closer to 3k.
 
I ran EC30 before VRP - but in your case with that burn rate it will be hard to maintain 20% or more - and HPL oils at that burn rate will be expensive and require filter changes …
If the soak is not a quick fix - consider VRP before EC30 … HPL PC.
(Slowest to fastest in 3 steps) …

Run Supertech Syn for the next three 1.5k OCIs. That should get rid of the quick ink look. Then concentrate on getting / keeping the dipstick oil to remain semi-clear for the first 1k. Then begin using EC30 with an engine flush in there somewhere.

This method assures slow removal of a messy, dirty engine.
 
Id be interested to see what BG EPR can do for your engine. I've used it twice 5000 miles apart on my 2019 Kia Sportage and well, I haven't pulled the valve cover off, bore scoped it or anything like that, so without a before/after to compare I can't say how much cleaning was done. But my oil still looks like this (see below) at almost 4000 miles in a car with 112k miles, FWIW.

I should also state that I'm using Valvoline Restore and Protect 5W30, this picture is from today, I'm near the end of my second oil change with it.

Make sure you get a really good filter for anytime you're doing some cleaning in your engine, be it a flush or short OCI, or a cleaning oil like HPL. My last two filter were a Fram EG and H/K OEM. Ill be moving up to a Purolator Boss or FRAM Endurance if I can find one for my car.

Wow thanks for all the replies! A couple things:
  1. Now that I think of it I overestimated how much oil it goes through, probably more like a half quart every 1k miles, not a full quart every 1k miles.
  2. I'm going to drain the oil this Friday AM and start the piston soak right after. I plan to go through a couple of bottles pouring in a little in each cylinder every 4 hours or so.
  3. I'll put the HPL EC30 and good synthetic in there after the soak and then will take it out for an Italian Tune up. I'll probably fill up the tank and add some Gumout w/Regane in there to let the PEA do a little work.
I didn't mention this but the last few oil changes have been Valvoline Restore and Protect just to see if it would help. At the end of this cleaning treatment I might give the BG EPR a try while I'm at it.

You can always swap out the filter early, like 2-3K miles into the OCI and top off too. Then cut open the filter and have a look at how much cleaning is going on.
 
This is what Dave at HPL recommends:

High Performance Lubricants

Thread 'High Performance Lubricants Engine Cleaner'

Since the topic has come up a few times I am posting the PDS in the PCMO, Diesel, and Euro sections. This is a safe path to clean varnish and or sludge left behind by other oils. There are no solvents in this oil. It has enough ester to clean but still be safe with elastomers. Simply add a quart to the current oil and can be used for 1-2,000 miles preferably but can be run longer if needed. Changing a filter at 2,000 miles is recommended should you wish to clean further.

And with the description like that, despite everything I've read, I can't help but think that the engine cleaner is meant to be the more powerful cleaner compared to the motor oil.

As it should be. HPL EC is specifically designed for cleaning internal engine parts, to be added to the engine oil for specified cleaning periods.

Ok I am going in, hold my beer! I am getting HPL EC to see if it can fix the oil hunger in my Volvo xc60.
