My daughter's 2003 Toyota Echo had oil consumption issues, by memory something like a least 1/2 a litre per 1000km (1/2 quart per 600 miles).
Piston soaked overnight with kerosene, the next day I idled that engine for 3 hours
with the crankcase filled with two quarts of PYB 5W-30 and two quarts...
Are you getting power on the vehicle's trailer connector?
If not, some vehicles like my 2014 F150 have a dedicated circuit breaker or fuse for the trailer connector/lights.
I use up a 18.9 liter pail of that Motomaster Semi-Syn 10W-30 Diesel Oil per year,
(regularly on special at 63$ CAD or so)
Didn't know it was a Citgo product, online searches I had done showed the exact same MSDS specs
as Rotella T5 but CT may have switched suppliers since.
Anyhow I've been...
In snowmobile applications, BRP specs an 0W-40 for the 600 & 900 ACE.
Operated and left out in well below freezing ambiant temps, these engines have
no backup pull cord to start if the battery/starter can't turn over the engine.
Myself have a 600 ACE in a Skidoo Tundra snowmobile,
oil...
Motul makes a 10W-30 gearbox / wet clutch safe lubricant,
Transoil 2T looks to be a mineral and is mostly marketed for dirt bikes.
They also offer a synthetic, Transoil Expert 10W-40.
Myself have tried every imaginable lubricant in my YZ125 motocross gearbox,
from thin Type-F to thicker...
They have been more and more visible in Canada in the last few years,
I often see their products in gas station convenience stores.
Total has a blending/bottling/distribution center in Montreal Quebec.
2014 Ford F150XL here with the 3.7 naturally aspirated V6 base engine,
truck I purchased brand new on which I installed a catch can within the first month of ownership.
(generic catch can in which I added mesh and a longer tube to better separate vapors)
Truck is not babied nor beaten, 25% city...
Apples to oranges comparision of course but,
I owned a 2011 Dodge Charger with a 3.6 and now a 2014 Ford F150 with a 3.7
To me, in general the 3.7 feels torquier and gets the same or better fuel mileage in a heavier vehicle.
One feature I prefered on the 3.6 was the easier access top mounted...
Despite not knowing it's origins I too hope that it's simply re-bottled Rotella,
nevertheless it has become my go-to oil over the past year.
Initialy wanting to simplify oil inventory in the workshop,
I picked it for use in the: lawnmower, snowblower, generator, lawn tractor.
Unlike many HDEO...
I drove a 1500 / 4.7 for many years, operated in a relatively cold climate
where the oil snot build up was an issue from late fall to early spring.
Removing the plastic oil filler tube assy from the engine and wrapping it with several layers
of insulating tape pretty much solved the problem...
On high performance 2-stroke dirtbikes, low to mid throttle openings are mostly tuned by 'feel',
but the method linked below is commonly used for wide open throttle jetting:

A while back when I drove a 2004 Dodge Ram 1500 4.7 liter V8
I had a front to back custom mandrel bent true dual exhaust with an 'X' crossover
and experimented with a few mufflers in the following years.
-Gibson
Quiet but were very restrictive at higher rpms versus the others listed below...
Two dirtbikes here,
a 2010 Yamaha YZ125 (2-stroke) for closed course motocross
and a 2008 Honda CRF250X (4-stroke) for trail / off-roading.
(a somewhat milder 'enduro' version of an MX race bike)
Engine wise:
as soon as the season ended the YZ got a new piston & ring,
a high winding 125...
