Yaris 1.3

[Badcompany]

Hello Forum,

This is my first posting so I would like to say Hi to everyone. My new Yaris arrives at the end of April, I would like to know what is the best way to run the engine in. I have read articles on the net that say, the best way to run a engine in is to run it hard for the first 50mls, ( After the engine as reached temp.) I have also read, drive it carefully around town for the first 500mls, no motorway driving. What do you all think.

Hi,

Most moern engines are 'bench run in' nowadays, in other words they don't really need to be run in the same way as engines from a few years ago. That said however I certainly would take it easy for the first 500 to 1000 miles just to bed everything in (inc brakes, clutch etc) and I certainly wouldn't run it hard at all.

That's what I've always done in the last 6 new cars I have bought and will do that with my new yaris which arrives at the end of april like yours. Which model are you getting?

Hi nellyp,

Thanks for the reply, I'm getting the Yaris 1.3 Sol, ( I live in Holland.) I think the English version is the T3.

Drive like a nun on a Sunday afternoon! Look after your car/engine and it will look after you. Basically I will do 1000 miles to run in all the oily bits and pieces. Brakes need to bed in as well. No motorways or sudden acceleration or heavy braking. Normal but varied driving will suffice.

New tyres are as dangerous as worn tyres for up to the first 100 miles (300 according to some books) they need to be gently run in as well, and that can increase their life by up to 20%. Most come from the factory coated with something called a release agent. This is a super-slippy coating designed to make the tyres drop out of the mould. It also happens to be super-slippy on the road.

We have just returned from our round trip to the South of France and 2200 miles later our 08 TR 1.3 returned 47.5 miles to the gallon...we run the engine in for the first 500 miles with no hard acceleration and then it was normal motoring with nothing above 80 miles an hour on the french roads...we are very impressed with the mpg, but it is not as good as the Yaris Blue 1.0 54 plate that I use...this averaged 50 mpg over the same holiday last year...these are cracking little cars and we love both our babies...like a new bride just treat it gentle.

Hi 4raver,

Have you had any problems with the brakes or clutch like alot of people on this forum.

The clutch no problem...the second gear a bit crunchy at first, same as the second gear on the Yaris Blue and the front disk brakes sound like they have the wrong compound and a bit graunchy but they work very very well...if you have problems with the gear box Toyota will swap the gear oil for a semi synthetic that solves the crunchy gear change as for the brakes we have yet to see...Toyota are going to have a look at them for us next weekend though they say this is a feature of the new car....they new Yaris is a very well sorted motor and I love driving it....my 54 plate blue is a sweet car with only 28000 on the clock and is now perfectly run in.

Agree with all the above - think of the running in time as also useful for you to get to know the car as well :)

Incidently, the Corolla T-Sport here literally didn't start loosening up and feeling 'normal' until about 15,000 miles so don't worry too much if things seem a little 'tight' for a while!

I know this sounds contradictionary, with regards to other opinions BUT, you can be too gentle when running in aswell as too harsh!

Certain amounts of piston scratching, etc, is actually good for an engine as it allows for small pockets of oil to help lube the engine better in the long run. This was concluded by RiDE magazine when they tested running in proceedures against just thrashing a bike. over running in made a bike produce less overall power than its proper run in or thrashed counterpart although the latter may wear out quicker. Bare in mind, a bike engine will usually be used more harshly than a car's anyway!

Take it easy for the first five hundred miles, getting a bit higher revs/speed as you progress. One of the common mistakes is getting the car to say, 50mph, and keeping the speed and revs the same. You need to vary revs and speed to evenly beede in new parts and after the first five hundred, even rev to two thirds maximum, motorway speed.

There is absolutely no need to avoid motorways, just allow the car to warm up and just dont thrash it.

When you get the new car, it should have the running in proceedure in the owners manual anyway but most manufacturers err to the side of caution as it will be them that has to pay for any warranty repairs unless they can prove you thrashed te vehicle, prior to proper running in.

There's different schools of thought in running a car in. I know experiments have been done in Focus ST world and the findings were that the car that was driven hard from the outset was measured at producing more bhp and torque than the car that was run in gently. Probably maked no difference to a 1.3 Yaris though so I'd take it easyish for a few hundred miles.

If you put an engine on a test bench and measure the oil consumption/blow-by (i.e. how well the piston rings are performing) the results are pretty clear. A good run in will make the engine perform far more consistently and that is general be with better power and oil consumption.

Problem is to do this study effectively you have to do it with quite a few engines. The main flaw of the road test method of doing it is they are normally done ONE vehicle compared to another. The problem with this is the tolerence stack ups in the engine (bore roundness/diameter/ring gaps/honing angle etc.) can cause a varying condition even between two vehicles run in identically.

The ideal run in method on a bench is to gradually increase engine revs and load until the engine is being run flat chat. This is normally done over a number of hours. In your car this should be done of the first few thousand miles.

As for all engines being bench run in I don't know of any manufacturer who does that. A lot will have been run on a bench but only for a couple of minutes and not on a dyno bench (i.e. unloaded). This isn't sufficient to run the engine in.
