Thanks to all as you made me study a lot of the new technology now in what I now own. My My how things have changed! Low speed detonation is a real problem with DI engines like we have in our STs or especially turbo charged engines. If one lived through the fuel we had during the mid 70's, low speed detonation or pinging was a real problem no matter the fuel grade. With that in mind and the article at the end, I understand the throttle mode the increases throttle response and why it might not be a food idea! Ever wonder where the dreadful sludge come from in the bottom of the oil pan? The viscosity improvers that make that oil perform like a 40 weight at temperature break down to combine with the combustion deposits. The failed Echoboost motors I seen torn down YT, have shown me that oil changes and the proper oil and high quality and octane is required. Pushing a 4500 pound vehicle with a 163 cubic inch motor that a few years ago would be slower than a VW Micro Bus! https://www.enginelabs.com/engine-tech/oil-composition-direct-injection-low-speed-knock/

I always figured Ford sold part and cars! An example from a few years ago was the Corvette sales story. Sales of the cars themselves were not stellar and the brass thought about scrapping that line. That was until they found out they sold way more Corvette parts than cars and the parts were VERY profitable! On the oil thing, F1 will only let the teams run no less than 10-30 and burn only so much per mile/KM. The oil is used as a power adder etc. as it burns! The Voodoo specs 5W-50 and one of the Shelby engines speced 0W-50! Voodoos drank big parts of their 10 QUARTS of oil with lots of engines lost due to owner neglect! I will probably change to a 10W-XX soon as I do not like some of the blow-by carbonation on pistons of a couple of failed 2.7s. Mostly due to long oil changes no matter the brand of synthetics.

Volatility rates of oils was fun back in the 80's. When the valve cover started leaking on client's cars. 1st. thing I would ask was if it was Pennzoil or Quaker State. They were paraffin based and left the covers filled with crud! I've stuck with synthetics since the 70's. Ashless like AeroShell was the same thing in the Valvoline Racing but with different additive packages with Valvoline having more ZDP. AeroShell was GREAT for oil burners too! I still add a quart or two of Valvoline Racing (high ZDP) to my oil changes to my 08 Edge with 210,00 miles. That seemed to quiet down the cam phasers. With all of the metal pieces crushed together to make the cams move, i looked at them just like flat tappet cam contact that need extra protection and the ZDP.

Anything one can do to eliminate carbon build-up in the intake path is worth GOLD! Depending on the fuel quality from the distributor and the additive package that are blended in, either at the point of sale (Costco) or the source, build-up can be mitigated depending on the additive package. Ford specifies TT type fuel which has P.E.A. detergent, Shell w/ Nitrogen, Techron Costco to name a few. Most have P.B.A. but, it will not get rid of the high temp gunk on the valves etc. like P.E.A. The catch can is cheap insurance for a KNOWN PROBLEM. But hey, like the "Fram Man" should have said "You can pay me now and you can pay me later". How much later depends on you. For the "Tech Wienies" who want to know why, here we go. 5W-30 motor oil is thin and gets thinner as it heats. I do not care for the 30 part as it only goes to the "holding ability" to keep parts apart. With thinner ring packs, short skirts (I like short skirts), thin oil, high R.P.M. and turbo boost will produce tons of blow-by. It consists of misted oil whipped up in the crank case by the crankshaft spinning and leakage of combustion products and coked oil that was burned about the 2nd. ring on down the piston skirt. Remember those "short skirts"? Well at high R.P.M. they allow "piston rock" where the piston is not square to the bore. With the wider gap in the rings to prevent them butting together and piston rock, excess "blow-by" is produced ! In our turbo engines that gap has to be wider than a N.A. engine. That gap provides extra "blow-by" that we are trying to cut down with the catch can.

Hey thanks @Haz, Like most of the things, that at times I kept running, for some of my less that financially able clients, have gone to the crusher! The technology that I was preparing myself for way back then, saved me countless hours of frustration when it arrived in the automobiles od the then future. The thing that sorrows me the most, will be our cumulative knowledge not found in the service manuals we used to make a living with.

I guess after a year of lurking and "freeloading", I should introduce myself here. I have a wonderful Ford stable. My foray into Fords began with a 427 63 Galaxie 500 which would handily outrun the cops (on several occasions)! We now have a 92 Mustang GT, Explorer 302, '08 Edge Limited and our new baby a '22 Edge ST. The "Black Momba", has 285/35 22s on Axe wheels with Goodyear Gatorbacks to keep the road slash down. Also, I've installed the ST puddle lights in the mirror for my wife's birthday, as after all "HER HOT ROD" this time. I have wrenched in dealerships from Ford, Lincoln/Mercury, Mazda, Fiat Jeep, Lotus Saab but, the Italian, Fiat Ferrari were the money makers. I don't go fast in a straight line anymore but, I point out to the new uninitiated riders where the grab handles are so the can hang on around corners! DE KI6FG

We found a used 2022 Agate Black ST with 16K miles. It was from Prosper Ford (a Berkshire Hathaway owned Dealership) Prosper Texas. 285/35 X 22 wheels and tires, a 401A helped knock it out of the park, especially with the "Bait Price". Carfax said minor damage but, I sure can't find it. They covered a small rock chip on the passengers with the advertising sign that after sale they would not fix. I just did my 1st. oil change, this week-end. At least one does not get the "Windsor Splash" when changing the filter! While looking the under-hood area over by the battery, I discovered a Lo jack wired to the battery and it was LIVE!! I had purchased a OBD2 Bluetooth for Torque Pro but when I pulled it out the OBD2 port came apart with a small wire running somewhere into the dark of the dash! I was fixing to ask questions here as I've NEVER had a OBD2 port come apart! I pulled the fuse access cover above driver's left knee. Low and behold I've now found my 2nd. GPS Tracker! Both were working and phoning HOME! Beware of Berkshire-Hathaway(BRK) dealerships. The CRAP they try to pile on is B.S. and Zaktek finish they pile on is owned by BRK! It is possible they are tracking their customers post sale? DO NOT let them "run the paper work" on a tablet or other electrical device. Make them put it to paper! Stand FIRM and be ready to walk no matter what! Outlast them and be boisterous and loud. Make sure other customers know that they are trying to screw you as they will want you out the door! Oh, by the way, pack you lunch as it is worth thousands of dollars out of your pocket. I started wrenching in dealerships starting 1971.

http://www.leatherique.com/ This is the best stuff for Ford leather seats! It does not take off the surface color.

http://www.leatherique.com/ This stuff is better than all of the other stuff mentioned above! Reserve at least one day for the Rejuvenator Oil to do it's job before doing the Prestine Clean. As a side note, it will leave your hands so soft that your girl friend or wife will want the "treatment" too. It may be pricey, but well worth the cost!!! Gary
