I tried to search this (but I suck at it) My dealer(service manager) told me to wait till at least 10,000 to change to a full synthetic oil to let the motor break in properly. B.S. or does it make sense? I know there will be a lot of diff opinions but w/enough response, maybe the majority will help me decide. So what do you think, what did you do? I bet there is a lot of you that think that the synthetic is a total waste of money and that's fine, lets here from you all to. Thanks
If the motor is not broken in by the time you drive it home, it will never break in. Change to it on the first oil change. Do you have any idea how many engine revolutions there are in 5k miles? A bunch. He is covering his butt and the companies.

Ive dropped the plug @ 1K on every new vehicle Ive owned the last 20 years.
FULL SYNTHETIC is all they ever see.Ive run extended OCI's long before it ever became popular,dino oil can not handle extended service therefore full syn shakes out on top in cost effectiveness as well as overall performance.
UOA's DONT LIE !

Sorry. UOA'S?? (I know this will be soooo obvious when I see it)
synthetic is overkill and a waste of money unless the manuf calls for it. just look around at all the trucks with 150-200k miles on them running dino oil and they are still running strong. heck i have a 96 neon that has 150k on it and its no where near maintained properly- probally an oil change every 10k miles or so on regular whatever jiffy lube has type of oil. i checked compression on it the other day to rule out a head gasket issue on a misfire code and compression was only about 5 psi down from what it was brand new, no where near worn at all. some people swear by it for some reason. oil analyses are worth the paper they are printed on if the truck still works fine then who cares. but theres people out there that think they have to run premium fuel in a truck that specifies cheap grade fuel, and people who think they need to put nitrogen in their tires instead of free air and people who just like to blow money for no apparent reason.
If you plan to keep the truck for a long time it's not a waste, however, I would only use full synthetic if you plan to tow a lot or do a lot of starting stopping or stop and go. These things will break down convetional oil quickly.
If you just drive normally I would save money and buy conventional or maybe syn. blend.
I run synthetic because I tow 5-6 days a week and it's constant start and stop. JMO

A friend of mine has a Mitsubishi that came with full synth and the manual says to change it every 7500 miles. That seems reasonable to me. 10,000 might be pushing it but maybe not. Synthetic does last a long time. I'd be more concerned about the filter and such after 7500 though. Also, oil change intervals are always tied to "service level" or whatever the mfgs call it. If you are a "heavy duty" user they always say to change oil more frequently (also in dusty conditions).

Maybe you misunderstood my question? I asked whether to wait until you have 10,000 miles to change TO synthetic, not to go 10,000 miles between changes
I've got news for you and your service manager. Your Tundra had synthetic oil in it since the day you drove it home. 0W-20 is only available in a synthetic and that is what is put in at the factory. This has been stated by Toyota.

You are 100% correct that syns are better for extended changes.....only problem with that is that while under warranty, extended change intervals aren't very smart.
