Other than wasting time/money - what drawbacks are there to 3k syn OCIs?

You keep spouting this nonsense over and over again but where's your proof of this?




Overly frequent oil changers are literally throwing money away on unnecessary oil and filters *and* creating the conditions under which intake deposits form. Worse, the OEMs have basically forced the oil industry to reduce levels of valuable anti-wear additives such as ZDDP because of actual consequences of overly frequent changes. Overly frequent changers are basically selfish and have ruined some of the highest quality long-drain oils "for the rest of us".

Say What!!

Many of the worst cases actually came from dealers and quickie lubes, for which substitution with bulk dino instead of the manufacturer spec'ed synthetic was likely (lets call this "fluid fraud").


Sounds like a problem with that design of engine or using the wrong type of oil to begin with, not a problem with changing the oil too much. If it were such a problem, then new Corvette owners would be having huge problems with their engines, because a huge portion of them will change their oil at ridiculously low intervals (under 3000 miles)

I'd like to see an official study, not just hearsay from some forum you happened to hang out in. If you do a google search on frequent oil changes causing problems with direct injection, it comes up with NOTHING. You'd think it would come up with at least one hit if it were such a problem...

Exactly!

Also, even though it is in reference to help with LSPI prevention, and not intake deposits, but I keep hearing that a good dose of ZDDP is actually beneficial for the prevention of LSPI in DI/GTDI engines (by what function has never been explained to me).

Agreed. Some of high whp Camaro LT1 guys does short OCI for years.

So these 3k oci's no way couldn't have waited till 5k? I don't believe that. I don't think these early oci's have saved any engine wear, in fact they might have increased wear. Wasting good serviceable fluids is almost sinful. OCD behavior in a lot of cases may not be harmful but in this case I would say it certainly is in more ways than one.
