@gtstang462002 I basically agree as with most vehicles using the engine oil change monitor is probably fine. I'm a bit more OCD with my Coyote at 12:1 compression and driving it in a spirited manner a few times. So - I err on the side of caution as IMO using Full synthetic and oil filter...

@Frogdog1 ..... if your intake is reading close to ambient temperature that is very good! The snorkels that lead from each air box to the front of the grille bring in the coolest air possible - air that is hitting the grille as you drive. The alternative used to be air that entered the engine...

@A_Z .... yes I agree and I believe they use the "standard" oil their dealers provide which is Ford Semi Synthetic 5W-30. I know this because I got my first three oil changes "free" as part of a dealer purchase package but the oil is NOT full synthetic, because Ford considers semi synthetic...

The type of oil (semi or full synthetic) has nothing to do with the logarithm. It is time and mileage based. That said there have been some interesting arguments - particularly with third party warranty companies like Lubrico - when a customer doesn't put the mileage on but shows an oil change...

You better not RSA Mustang at 2000 WHP. It'll gap you real bad.

Tests of 0 weight oils show they do not protect nearly as well as 5 weight in high temperature internal conditions. I tried 0W-30 Full synthetic ONE time in my 2024 GT for winter storage as I start it every three or four weeks and run it. The engine "noise" is considerably more pronounced with 0...

@GTSteve ..... great work. I particularly like that you matched the grain of the dash. The "grain" of the dash was a specific pattern researched by Ford to break-up any reflective light patterns that would reflect onto the windshield like about 80% of other vehicles. You may have noticed that...

@Vapor ..... you are probably in the 1% club that actually know how to use a pressure washer. The rest damage trim (painted plastic) and drive water into body cavities.

@Starship Enterprise ..... 100% correct. Decades ago, my family built a set super expensive HP marine racing engines for a client as they started to get into marine. We wanted to sell him our automatic oil removal oil system. We told him , we will remove the oil pan drain plugs, install a cross...

@AZ_Ryan ....... do I hear the song "feelings" playing in the background? That's pretty thin AZ. I agree you can hear a different sound with some of the aftermarket filters but can you feel that at the pedal? "Feelings" keeps playing. Just sayin' ..... Do agree that no one can notice a 6HP...

Body shops love owners who pressure wash their cars - kills paint jobs - drives water vapor right through clear coat, paint and primer. My local paint booth spray god said we should give pressure washers away with every new car as 99% of the idiots will ruin their cars, boats, house siding and...

@Junkyard Dog ..... that would be correct. There isn't enough of a change to notice that. We ran dyno tests on switchable exhausts connected to CMI headers to account for various no wake zone decibel readings and there were not measurable differenced between the final selections.

@Eli GT ..... agree 100% with all you say and I repeat - if you want 5W-30 FULL synthetic you will almost certainly have to purchase in bottle/jug format to give to the tech. IMO that is the only way to guarantee you get 5W-30 FULL synthetic.

@Frogdog1 ..... you can bet your Mustang that temperature makes a huge difference, humidity does too but not as much as temperature. Altitude makes a huge difference. When we were building high performance marine engines for owners who boated in higher altitudes we would have to re-gear their...

@Neggytive .... kudos for tipping the tech. the word spreads fast and soon everyone treats my cars like glass. Telling the service manager is also a great idea. As for the dealers using oil out of drums you are also correct. I posted about this on another thread in this forum but fast...

......and the hardest thing on any engine is a short drive. You live in the south and drive short distances ..... geez, change it a lot! :-) The water vapor and acids never get burnt off they just keep polluting the oil. There is NO rule for oil changes. As many have said on this great forum...

Yes, altitude can make a 'uge difference as can humidity and temperature, You may feel your car is "crisper" and it may be - but - I'd bet serious money no one on this forum can detect a 6 HP difference on a 480HP engine. We had owners who we adjusted say a 383 from 400Hp down to 390HP to settle...

RSA had a 2000HP wheel rating a couple of years ago on their twin turbo project. There were some great internet videos of it slaying anything that came near it.....lambos, you name it. I didn't read the literature but you will need engine and that kind of HP. Fun though!

Define safe. Higher octane runs cooler despite any attempt at timing retardation by an engine Higher octane has components that protect valves not even dreamed of in lower octane fuels. Is your 87 really 87 I ask because 87 is IMO totally borderline for engine damage in the Coyote so if you have...

@DarkMatterGrey ....perfect. My grandfather started a construction rental business after the Great Depression. Companies couldn't afford to purchase machinery but could rent it. He had everything from small engines to big earth movers. He employed 15 mechanics at one time. The reliability of his...
