I can't speak for him, but in my case, it was the consumption of large amounts of controlled substances during what was, in hindsight, a mis-spent youth.

Doesn't matter anymore? Well...it matters if you plan to keep the car over 100K miles.

That's absolute nonsense and you have NO evidence to support your comments. Post it if you do.

My two Toyotas have been owned by me since new, and I ran both of them out to the manufacturer's suggested OCI on the first oil change. Neither one consume abnormal amounts of oil now. And according to the records I got with the Accord, the previous owner did the same. So my anecdotal evidence is that it doesn't matter one bit.

Please support your 100k statement with facts.

Really? I wonder when mine are supposed to/scheduled/engineered to retire.

Your statement makes for a good sound bite on the board, but just like the 100k statement I'd like to see your supporting evidence. Sounds like nonsense to me.
 
I dropped a rebuilt engine in my kid's car and the rebuilder makes you do the first change at 500 miles and then 3000 miles after that. While excessive, it's what they demand for warranty purposes.

Mom & Pop shop can't compare with real engine manufacture like Honda.

Their assembly rooms are much cleaner and their techniques are much better.

Mom & Pop shop OCI recommendation for a rebuilt engine is not applicable to a new engine manufactured by the car companies.

Honda very adamant about keeping FF to full OCI because of special brake in oil is used.

My 21 years old LS400 with 370+k miles had FF drained at normal OCI of 7k miles.

My 15 years old E430 with 170+k miles had FF drained passed normal OCI of 12k miles by several hundreds miles.

Both engines are running great with original valve cover gasket. No engine work is needed for either car. Oil consumption is the same both both cars, 1/2 qt at around 3-4k miles for LS400 and none for E430.

Dump FF early at 500 miles or 1,000 miles may prolong the engine life to 500k-600k miles, but other parts of the car failed way before that.

True indeed..... unless abused or if not taken care of per manufacturer recommendations no modern day engine will die early as proven to me in my 2 hondas and 2 toyotas past 5 years.

If there is a proof with data for a big improvement by changing FF early i will be the first one to do so.
 
It really comes down to one's comfort level. If they want to dump the FF at 1000 miles, who really does it bother? I have always been a fan of not only dumping FF on the motor early on, but the entire drive train on all my vehicles. All drive train fluids changed within 3000 miles. It is my comfort level. If someone wants to do all their OCI's at 1000 miles, no big deal. Heck, change the oil weekly if it helps you sleep better at night. Not everyone is interested or has the comfort level to go as far as is possible on oil and lube changes. While I do dump FF early on, I generally have no problem going out to the OLM or manufacturer recommend intervals, and sometime even longer depending on the vehicle in question.

And if you saw the magnetic drain plug from both my 2013 1500 Silverado and 2015 2500HD Silverado pickups at 3000 miles, you would understand my wanting to do it early. Both plugs had so many wear particles on the plugs that it was if someone had stuck my cat's tail in a light socket. The 1500 rear diff was over 1 quart low on the FF, and the 2500HD rear diff was 2 quarts low on FF. Front diff on the 2500 was below minimum recommended level. So given this anecdotal experience, I will always dump FF on everything within the first 3000 miles at most. Motors will always get an oil change before 2000 miles.

It is a fact that such 'debris' does indeed pass through the oil pump in most designs but it certainly does not harm anything. And oil filters do indeed filter out particles that are large enough to do any damage......


What makes you that delusional? The oil filter makers all admit they only get out down to around 20 microns. Oil films are near zero, below 20 microns all over the engine. Any iron or aluminum particles you can get out from a new engine below 20 microns is beneficial. Lots of machining dust left over in a new enginne. UOAs prove that. But then, people like you don't need proof. I've read your posts and you never have any real facts.


Neither do the early changers. None. Just imagination.

Oil filters do indeed filter well under 20 micron particles. They are not a barn door! They just don't claim to catch them all.

I just sold a 2004 GMC van with over 500k miles on it. A 6.0 that never had an oil change unless the OLM said to. We own a fleet of those and some Silverados as well.

Facts are hard to find, eh? I don't care what you think at all, I do what really works and make my living by those decisions...
 
I changed the oil at 1k to remove whatever break-in debris was present. The dealer then changed the oil at 5k so the first two OCIs were 1k and 4k. I'll do the recommended 5k OCI going forward. I'll probably change the lube in the gearboxes at 10k to Red Line and maybe again at 60k. So long as no one hits me and totals the truck I should be able to keep it for over 20 years and that won't even get me to 300k miles. I expect internal engine work to be zero.
 
Ok - after reading a lot of opinions, I'll change out the oil myself at 3000km so I can install a EZ drain valve (or Fumoto). I will ALSO send off my oil to Blackstone to see how it's fairing.

I want to see if there really is a molly additive or if its just baloney. From my analysis, if there is a lot of particles in the oil, I'll report back here on future recommendations for early oil changes on new engines...

If it's the factory fill you might find high moly in the UOA. All that means is there's probably moly from assembly lube, not necessarily from the oil's add pack. You'll probably also see high wear metals..........No comment on that.......
 
I've always done 75% of whatever the factory oci is for first change. And after that whatever oci the manual recommends based on my driving style. And always drive it like you stole it a idle or consistent rpm isn't good for new engines you need to hit fluctuate thru the engine rpm range

...and that's why I bought the XT 2.0L Turbo version of the Forester...a whole lotta fun in a family hauler...

Based on your advice demarpaint I am going to wait on the Blackstone - I'll do that on my second oil change.
