no, im just curious as to why people do different things... just learning

Well, FR-S10, I think what we have here is a "old school" vs. "new school" (or old, new engines vs, new, new engines) thing working.

(that outta get ol dttaz all twisted up .... :D.)

Back in the day, when engines were machined, lots of metal shavings were present with a new engine, thus many felt it was a good practice to flush out the "break in oil" after a thousand or so miles ..... to get the shavings out of the oil and most that settled in the oil pan.

It's my understanding that modern engines are machined closer and produce much less by-products of the parts getting used to working together. Thus, a longer interval before the first oil change.

The use of synthetic oil extends the interval even longer.

So, ya wanna be old school or new school ... http://www.runemasterstudios.com/gra...mages/wink.gif

I find it quite funny that dealers recommend as low as 3k oil changes when it is on the customers dime. But if it is a free maintenance program its 7500+. Was in waiting room and this lady just got her free oil change on a VW Passat and they told her the next one is in one year or 10k miles.

:bellyroll:

Supposedly, the factory fill is different from the Toyota full synthetic used at the dealers and helps with the proper engine break-in. Metal shavings? Debris? That's why there's an oil filter.

Unless you're going to the track or drive under the severe conditions described in the owner's manual, 7.5 months or 7.5K miles (whichever comes first) is the recommended interval.

I don't know of anybody who ever had a problem when following the recommended intervals in ANY car unless there were mitigating circumstances.

Oh, and the 7.5K interval is because of the boxer engine - for most cars today using full synthtic, the normal interval is one year or 10K. On some high-end cars the computer monitors the oil and tells you when it's time to change based on the conditions. I imagine this will spread across all product lines eventually.

i think a good time would be around 5k

That's why you should just do a used oil analysis with TBN. No thinking required! Most stock engines can easily handle 7,500 mile intervals.

So middle school then. :confused0068:
