Has anyone actually followed these instructions? If so, did you actually notice a difference?

 

yes, i think that this guy knows what no one else does. i also think he's the one sending me e-mails about making my ***** 5 inches longer and wanting me to help him with his Nigerian bank problems.

but then...he's talking about bikes, and i don't know **** about bikes.

 

Thats the way I did mine. My dad is a diesel engine mechanic and thats how he has always broken in all his rebulit motors. I can't tell you the difference from running it soft because this is my first new car but I can tell oyu my G has no issues. Hope that helps.

 

All I can say is that I redlined my car on the test drive (car had like 4 miles on it) and it runs fine. Before my greddy tt I dynoed it and it put down 232whp on a dyno jet.

 

This is an eternal debate in the car circles.. but one question -- if it really is the way to go, why isn't everyone, ok, more than this ONE GUY talking about it. Forget for the moment the potential greed of the manufacturers... what about the magazines, car shows (even the non-profit ones on PBS). Not one of them ever endoresed this method.

The argument is persuasive, I'll give him that, but at the end of the day, I'll go the warranty prescribed route.

The author asserts that engine manufacturing techniques have changed or evolved and the old engine break-in approach mo longer applies. However, no explanation as to why the manufacturers missed this "fact."

Infiniti, and indeed any automotive manufacturer, has it in its own best interest to optimize engine break-in and minimize abnormal wear and tear so as to minimize costs under warranty and also to maintain high consumer confidence and satisfaction.

The periodic anectdotal post by a few individuals that ignored the manufacturer and drove their car hard from the first day without apparent damage and have observed no ill effects should be considered a testament to the durability and reliability of the G35's engine - not a justification to ignore the manufacturer's instruction on engine break-in.

Interestingly, in general terms all of the automobile manufactures and also diesel vendors in electrical power generators and engine manufacturers for boat engines all offer the same general guidence. Limit load and/or rpm and avoid rapid excursions and also avoid prolonged operation at constant load or speed. They all can't be wrong.

 

Actually I'm breaking in my new engine on the dyno just like it says on the website, I'll let you guys know how it goes.

 

The reason I'm asking is that I'm getting a G in a few months and it's going to be my first new car. As some of you mentioned, the author of that website has valid points, but it's strange how it's not as ubiquitous as it should be if what he's saying is really true. I'm still undecided on how I'm going to break in my new car, but I'm very interested in what those who have tried, or will try, this method to break in the engine. Keep us updated, tony!

 

I've heard many intelligent people state that engine break-in and driving safe applies to old cars, not new ones.

My last car was a VW. I learned how to drive stick on it and drove it very slow for a while until I got the hang of it. I had to have my engine re-ringed at about 60,000 miles. Several times, the mechanic at VW (for like 20 years) told me that the break in in those cars are important. The ones they get back were not driven hard enough. He said the best way to break in the engine is to drive the h e l l out of it. He even told me that they would intenionally take out new cars for a 200 mile trip and keep the rmp's high to help break the engine properly. A VW tech told me all this.

I think manuals state this because they are playing it safe. Do you really expect to read a manual and have it state "Drive the hell out of it."

 

Hi:

I bought my '82 Supra brand new, off the lot with no test drive. I broke it in slowly with extra oil changes. After 23 years and with 235K+ on the odometer, the engine runs fine! I take it on long trips over mountain passes and across the hot desert with no problems. It does not consume oil!

My "89 Supra was bought used with 60K miles on the car. It was originally owned by a woman professor. It has consumed oil from the day I bought it. However I think that this car's problem was caused by an undiagnosed partially stuck open thermostat problem.

My 2003 G consumes more oil than my '82 Supra, but from what I read, the G's engine tends to consume a bit of oil. This G had been test driven by others before I bought it and I test drove it hard. I broke it in easy with lots of deceleration time and with excessive oil&filter changes at the distributor. Hopefully this will pay off in engine reliability in the years to come.

The guy on the web site is talking about motorcycles, which tend to have shorter life spans for their engines. Also, diesel engines have a very narrow rev range which might allow them to be broken in harder. If you decide to drive it hard during breakin, stay within the rev range and allow the engine to decelerate back to 2K RPM before you WOT up to the upper limit of the break in range.

Which ever way you choose, enjoy your G!

 

I break my rides in by the book no matter what someone else has written.
I think Nissan/Infiniti knows the most about this subject.

Says the OLD man with an 'M' not a 'G'

Just playing w/ ya 'M'sedanMan

 

The book (from dealership) will say on most MT cars that WOT is good during breakin in gears higher than 1 (so everything but 1) but not to redline....

I dont know if our book says this but my friends Z28 had a whole page about it...

 

not trying to hijack, but what does WOT mean?

 

What i did i just threw a brick on my gas pedal while the car was in neutral and left it there until i saw smoke comming out from the engine bay>thats when i took garden hose and spray the whole engine with nice cool water,3000K on the car and still runs like NEW!!!!!
