Oil formulations were better when the gov't wasn't in them imo. They even used to have real synthetic as synthetic oils. They have made some advancements, but have made it harder for oil companies to make an oil for the marketplace and not to gov't garbage standards.
That's funny because engines last 100s of thousands of miles longer at way tighter tolerances and way higher stresse.

Any collectable data says modern engines with modern lubrication are infinitely better.

So you think the m1 you buy off the shelf today with low zddp, low calcium, and group 3 mineral oil, is better then the mobil one of yesteryear with pao, high zddp, and high calcium? Let's agree to disagree.

What I will agree to is despite the difference in lubrication it hasn't hurt engine life. Personally I believe it is the forgiveness in the engine application as opposed to some great advancement, but we probably disagree on that as well. To date no study proving synthetic over conventional will give you longer engine life, so no way can we say either old synthetics or new synthetics can give longer engine life.

What has driving oil formulations of today is completely different from what drove oil formulations of yesteryear. The gov't is in charge now, before oil companies used to try to make the best product for metal to metal wear as they saw it.

Wow, so they are doing a heck of a job increasing longevity and durability over what the oil companies of the past were doing.

Try this, what about the new formulas exactly are better then old formulas? mineral oil better then pao? Low zddp is better then high zddp? Low calcium is better then high calcium?

Oil is better than it has ever been from Dino up to group 5 but the issue that is present is companies not disclosing the actually type very well and using misleading statements like full synthetic when it really wouldn’t have been considered true when synthetics came to light.

Just do some very unscientific research, listen to a variety of newer cars that are idleing as you walk by. It's not only ram, there are alot that have tics.

You should have heard them in the 60s, 70s, 80s, 90s. Engines rattled like hell.

Mine never had a tic unless I was running solid lifters, and then it still wasnt that noticeable.

I disagree, all my older vehicles were much quieter at idle than my Hemi/most newer vehicles I hear idleing. If any of my old small block Chevy's rattled and ticked like my Hemi used to, it would have had a serious problem. My Hemi used to tick pretty loud at idle when it was hot but since switching to a higher quality oil it's much quieter now.

Overhead cams alone quiet tons of valve clatter by having less parts to rattle. Noisy timing chains have been replaced with timing belts that make almost no noise. Internal bearing tolerances are more accurate and consistent than ever before creating less space to have movement.

Seeing as none of us can go back in time to buy a new car it's moot anyway.

The longevity alone is solid proof. If parts were just beating around and ticking all day long engines would beat themselves to death.

Dispite the quality of engines. The off the shelf oil of today is progressively reducing anti-wear additives, AND other important things like calcium STRICTLY because of the EPA and cafe trying to reduce air pollution out of your tail pipe. The changes to Your catalytic converter is another byproduct of big brother, epa, cafe.

Bottom line. Even if the off the shelf oil base stocks (group 2 & 3) may be slightly cleaner today,the oil in a whole is not necessarily better anymore.

Its very simple IMO

Proof will come with this new GF6 standard. Its brand new. When my 6.4 running 40w redline idles quieter than my buddies 3.6 pentastar on 20w vlavoline... its because of the obvious. Oil quality. A ticing engine is not happy

Have to disagree that timing chains are by definition noisy. Properly tensioned, lubricated and maintained, timing chains (the high quality roller type) are as quiet as any timing belt, and MUCH more durable. The timing belts seemingly in common use now aways are being used for one primary reason; they are cheaper than a high quality roller type chain and their high quality sprockets and tensioners. With a properly designed tensioner, timing chains will last the life of an engine. Timing belts need to be replaced periodically or they will break, causing severe damage to an interference engine. Thats not a concern with a roller timing chain. The roller timing chains used in the newer iteration of Subaru's engines as an example, was done specifically to eliminate the need for periodic timing belt replacement.

I've got two quite long roller timing chains on the double overhead cam engine in my Boss 302. The motor is very quiet despite being taken to it's 7500 RPM redline numerous times.
