suppose you stopped for a 5 mins break. this is a case of hot shut down. the engine is still hot (parts like cylinder head, manifold, etc.) and this conducts heat into the turbo bearing area. that actually raises the temperature of the bearing housing to as high as 375 degrees C. so when you hot start, the oil actually helps remove the excessive heat so you should let the engine idle after a hot start. | |

| ![]() Thanks Blackasta and gansan Kinda got the picture and i seem to be doing what the majority do. Do anyone perform engine reset every now and then ( by removing the battery neg ) Does it have any effect on the engine? Do the A/C fan speed affect the mileage, or it will be the same of the A/c just being on? A/C in Chennai drains more fuel than in a colder place? Whats the best way to run down the running period ? ( taking out for a long 1000km drive on the highway keeping her at different speeds, may be break for few hours in the process ) ? Doesn't it seem like an impossible task to have an ideal break in period living in Chennai/ Bangalore.? Whats the influence of Tyre pressure on the engine? Whats the influence of different petrol pump, does different company fuel differ ? What if i alternate different fuel according to the availability, affect engine? Does the number of people in the car at all times matter to the engine (in the break in period) ? Is it not advisable to drive up a hill station during the break in period.? What if u strike upon an emergency and need to drive fast. Is you car engine gone forever? |

You could be reaching 80 in 2/3rd gear and ruin the engine. Normally its advised to keep it less than 3000 rpm. | |

BHPian | ![]() I am about to take delivery of my new Safari in a couple of days, and want to make sure I do a proper run in. A friend says I should let the engine idle for a couple of hours once after taking delivery. I haven't heard of such a thing anywhere - is it true this will help the engine settle better? Does anybody do it, or is it recommended? Please advise. |

Team-BHP Support ![]() | ![]() Idle for 40-50 seconds every time you start the engine, and every time before you shut off the engine. Do it during run in, and even after that. Other than that, during first 1500kms stick to 2500rpm limit. thats all you need to do. 2 hours running engine? this is weird. |

| ![]() I took delivery of My Punto MJD VGT last week.I have couple of doubts about running-in - (1) I have read here that it is better to idle engine for 30 sec or longer after car is started, but the manual mentions that it is better to build speed slowly after starting rather than idling it. So what exactly is preferable for longer engine life & smooher engine? While shutting down manual as well as recommendations here sugest idling befor switching off. So I will stick to that. (2) The first service of Punto is at 3000 KM and it doesn't recomend changing oil. Is it recommended to change oil at 1000 KM mark? |

| ![]() 1) What manual means is donot idle long and waste fuel, but a 15-30 sec idle helps in getting oil circulated inside the engine. 2) Its good if you change the oil first at 1k kms and then at company specified intervals. |

Point # 2: The engine oils now have very good viscosity specially Shell Oils. So 10 k kms is ok. My Take for running in: In 2/3/4/5 gears rev up rpm to 70 % of engine max power and bring down to minimum. Do this in ALL gears except first and reverse. Do not worry if that speed is say 120 kmph. Just touch that and let go immediately. Cruise at 80 kmph for 10 minutes and keep doing this procedure for 1k to 3 k kms. It is a bit painful so you have to selected roads like Expressways or high ways to do this. On the Honda City I pulled the car to 170 kmph during break in period in the 5th gear on the Expressway. I did this around 10 times over three days. Just touched 170 and let go. My process of breaking in process is called "Drive As If You Stole The Car!" ![]() Not really stupid. Skoda manual reccomends this procedure too. Drive Safe Rgds Commander Nandu Chitnis (Retd) | |

| ![]() I got my scorpio fifteen days back and have done 3000 KMs alreaday. It was nice to read about changing of oil after 1000KMs which I will do right away. We have done long runs on highway - was careful not to exceed the speed limits. Apart from this is there anything i am missing that i have to take care at this stage? |

Similarly I idle for half a minute before switch off, though the manual is silent about this. | |

| ![]() May be your Gypsy has a "King size" radiator! Different manuals give different opinions. At the MASS I have seen the guys start the cars and almost immediately move off. So IMO idling for about a minute is advisable, but not mandatory, as a measure of abundant caution. Especially if the car is started after a gap of a few days. |
