New FRS Break In

Changing oil early is throwing money away...

This is false! All the test dyno does at the factory is to make sure all systems are working as designed, and most that is done with the engine cold (I.e no spark or gas). They literally only cold run them for a few seconds. When they are in the car they get ran for couple of minutes at the end of an assembly line to make sure emission systems are functioning correctly. This is not a Ferrari where there actually put an engine on the dyno. Please inform your self before spreading this crap. It doesn't matter if it's a lawn mower or a new sports car, they all require a break in, to heat treat the aluminum and to help the parts to "wear" into each other for maximum efficiency, and longevity.

The break in period is kind of a joke tbh. Changing your stock fluids out before the first scheduled maintenance is also a joke and a big waste of money. Dealers push the cars well over 4k to burn off all the smells before customers ever get around to test driving or buying cars. Keeping your car under 4k for the first 1k miles is good/recommended and will more than likely help everything seat correctly but honestly the factory has already done all of that for you, as well as the people who move the cars onto the trucks from the factory. Part of their job is a "break in procedure" to make sure that nothing detrimental will happen upon delivery. It's more an urban legend/superstition than actual fact these days, however I don't recommend you go out redlining every gear under 1k miles but definitely stop wasting money on fluid changes right after you pick up your car. Nobody knows the car better than it's manufacturer and why would they put fluids in it that need changing in the first 100 miles and never tell anybody?

Wow is there a lot of different information here. First Toyota owns 81% of Subaru stock so of course they would carry a lot of the same information. OK lets get real, car manufactures do not make money by making car engines to last 500,000 miles. Of course they want you to wait to 7,500 miles for an oil change, this effectively will lessen the life of the car and they can sell more units to make more profit. Its good economics on their part. I have been an SAE mechanic for Ford, a Motorcycle mechanic for Suzuki Motorcycles and also did 22 years in the Navy working on multiple engine systems including, gas turbine, diesels, and other numerous types. I also worked in a military oil testing laboratory. The key to engine longevity is to keep the fluids clean. Yes I agree modern synthetic oil does not break down like oils of old, but it does get dirty, regardless of what does get caught in filters, you still have dirty oil with acid and other contaminates from combustion. For all the people who want to go to 7,500 miles please do, there will be more good parts at the scrap yard to pick through when your engines ruins a rod bearing. No thank you, I will do my first oil change right after break in at 1000 miles and every 3000 miles there after, or more frequent if it starts to look dirty. Oil is cheap, engine work is not!!!!

You got that 81% wrong. 16.5% is the right number.

"look dirty"
Why 3,000? Magical number?

Thanks SWARB, I had read 81%. Its good to see we share the same car DNA. Why 3,000 miles well its goes deeper then that. It also involves, time the oil has been in the engine, Never exceed 6 months. climate it is operated in, driver style. primary driving, city short stop and go cycles that the engine can not get up to proper operating temperature, excessive idling. In the military we do not use miles, we use hours of operation. From all the engines that I have torn down for inspection one thing I can say is the engines with less miles or hours in between oil changes looked much better on internal surfaces then the ones that ran extended oil change periods. Every single one of the engines that we have in our FRS or BRZ are a little different from each other. Even though they are made in the same factory, all engines are not alike. There are really good ones and really bad ones. They also vary in their hp at the crank 200 hp with 151 torque is the average. The production line that puts these engines together is not as strict as they are for some of the jet engines I have worked on through General Electric, or Allison. In regards to dirty oil, it takes a while to do damage. Dirty oil has contaminants, these contaminants start to collect on surfaces over time and eventually start to restrict flow to passages within the engine. Usually it starts at the top end of the engine, because it is the farthest away from the oil pump and does not get oil instantly on start up. Look inside the oil fill cover of an engine with 100,000 miles on it that has had oil changes at every 7,500 miles, then look inside the fill cover of one that has had changes at 3,000 miles. I will let you be the judge of what you see.

I didn't read the warranty till later this day a couple times I went past 4k up to maybe 5 or 6k rpms, and I'm only 217 miles on the car so far will this void the warranty? Since I've found out about it I've stayed below 4k.

Unless you blew up the engine ..... I doubt the warranty would be in question.

I suggest you set your rev alarm/light thingy to 4,000 rps for the first 1,000 miles, as a reminder.

Also, I suggest you settle in with a soda pop ..... and read the owners manual ........ yep, the WHOLE damn thing ..... not just how to set the radio and how to open the fuel lid......

Thanks! I appreciate it car is running fine I'm about to set it to 3,500 just to be safe!

And I'm sure you believe thicker oil slows down oil leaks... Car engines last longer today than they did years ago when the 3K mile oil change was common, and a hell of a lot of people don't take care of their cars the same way they did decades ago. Modern EFI has made the car into an appliance that many people won't even open the hood until steam is coming out or the engine simply shuts off.


One only has to go look at the oil analysis thread to see that the oil is far from spent at even it's normal interval...

This is kinda dumb. I can do a couple short trips in a car in cold weather and have the inside of the oil fill cap look like the car has a blown head gasket. I can also put a good synthetic oil in and have the cap be clean by the next oil change even on a car that ran conventional for over 100K miles (and what was visible of the cam and head in the hole was spotless as well).


Wanna know the #1 cause of a break down? Cooling system issues. Overheat an engine and pop the headgaskets and it doesn't matter what oil you have in there, cause water doesn't lubricate...

The cap? You can clean the cap with a rag. The cap doesn't tell you much of anything.

One change with good oil will not clean the valve covers up. Pull those after going 100k miles without changing the oil and then get out your mineral spirits to get all the shit off of them.
