My engineer neighbor's approach to oil change breaking in his truck ? -

A friend and neighbor, who is a retired engineer and has knowledge and experience with things mechanical, including cars, told me just now that he broke in his 1999 Ford 150 Lightning truck by changing the original factory oil at 1000 miles and then again at 2500 and then at 5000 and has kept to 5K, with synthetic, for changes since. I know that engines are machined to a greater quality of tolerances than those of 20 years ago, which then included a free dealer oil change at 500 miles to flush out the metal filings etc, but would you agree that it makes sense to use a break in sequence, such as this, at this time, with our new Toyota 4Runner - rather than the published approach, which is to just do nothing until 5k miles and then change to Synthetic, if I wished to ? I don't mind the extra expense, even the cost of synthetic, and filter changes, in exchange for any benefits that breaking in in a preferable way would provide, if they so exist. It is possible that such a break in sequence would be a bit too daunting or complex for non machine minded consumers and Toyota, although it might so prefer it this way, just leaves the change at 5K miles to simplify things. Thanks, Forrest |
any special break-in oil anymore). Then at 5000 miles switch to full
synthetic, and change it at 5000 mile intervals. The rings will seat faster
and better if you use conventional oil up to 5000 miles.

Well, Honda says specifically NOT to change the factory loaded oil early, because they say they load it with something special for breakin purposes. You might ask if Toyota does anything similar. |
they just don't want people switching to synthetic too early. I suspect it
is the later.

have to screw up their car it's them. If they feel that making you
change early would make their car lasts longer they would of say so.
Since they didn't, you can bet that you really don't need to change it
early.
It's hard to deal with paradigm shifts, but technology does improve.
This country took 30 years to get people away from the 1,500 miles oil
change interval to convince them that they really only needed to
change oil every 3,000 miles. Now it seems like it will take equally
long before people really believe that you can last 5,000 miles
between intervals on regular conventional oil.

Always go with manufacture schedule. If there's anybody that don't have to screw up their car it's them.

determination in what the maintenance intervals are (since warranty costs
comes out of their budget). Marketing and sales looks very closely at what
the competition says, because maintenance schedules can be a competitive
advantage when trying to sell one brand over another. So it is not entirely
an engineering decision as one might think.

the customers to change oils more often, not less.

engineer neighbor described is because it is not necessary for Toyotas.
Believe it or not, the folks at Toyota are pretty knowledgeable about the
products they design and build. I spent 15 years working for the automaker
and have broken in close to 100 new Toyotas. You will not go wrong
following the advice in the owner's manual - that is what I do. ;-)
If you change the oil too soon, it takes longer for the rings to seat and
the engine will get poorer performance and poorer fuel economy.

Then it would be more pressure to add unnecessary intervals to scare the customers to change oils more often, not less. |
interval. Every Honda salesman knows the differences (if any) between the
Honda and Toyota maintenance interval, and if it is to their advantage, the
will mention it to every customer.

rebuilt motors most of the race-engine builders i know change every 2K
miles until 4 then switch to fully synth at 5K and go as normal from
then on. Thats said my engine has a recommend oil change rate of every
2750 miles :-O according to Mr T lol.

Thanks, Forrest The reason that Toyota does not specify the break-in sequence that your engineer neighbor described is because it is not necessary for Toyotas. Believe it or not, the folks at Toyota are pretty knowledgeable about the products they design and build. I spent 15 years working for the automaker and have broken in close to 100 new Toyotas. You will not go wrong following the advice in the owner's manual - that is what I do. ;-) If you change the oil too soon, it takes longer for the rings to seat and the engine will get poorer performance and poorer fuel economy. So what if you only have about 2500 miles at six months (and not the 5000) - give up one for the other? M |
best thing to do would be to take a 2,500 mile road trip.
The worst thing you can do for a vehicle is take short trips without ever
getting the engine, transmission, and exhaust good and hot. Nasty stuff
accumulates in the oil, the exhaust doesn't dry out so it corrodes more
quickly, the tires get cracked, etc.
Otherwise, change the oil based on time, not mileage.
