Running In

Running in

I have read various articles in magazines and on the net, trying to find the best solution to running in a car. I have been told that the best thing to do is to run it hard and seal the piston rings within the first 20 miles. After that, take it for an immediate oil change to wash out any bits of sh!t left due to the boring of the engine. Replace the oil with semi sythetic and run hard again for the first thousand.

I have heard also the exact opposite

Also, do you guys and girls use shell Optimax and if you didnt use it and then started to, did you see a significant performance increase to warrant using it continuously

MOST people on here will tell u to follow the manufacturers guids ! eg stay below 3500RPM for 600 miles etc ! and optimax is a funny topic some peeps say its the dogs danglies and others say its as good as supermarket petrol ! The choice is up to u ! Whether ur wallet will allow it ! If i had the money i wud ( I use BP ultimate ) .

 

[JAY172]

Do about 850 miles of steady driving and then after that you can thrash its ass off.Ive tried optimax but didnt notice any difference to using normal petrol.

Moderately thrash it from new and get the oil replaced with decent synthetic stuff after 1000 miles.

 

[Chad]

I try to use optimax most of the time and I find my car ticks over better when cold and feels more responsive.

I ran mine in properly mate and with only 2700 miles on the clock it ran a 14.5secs 1/4 mile with only a Viper, so taking it easy aint done mine any harm!

In fact, thats bl00dy quick for basically standard!



Yet my mate mailto:r@ped">r@ped his from day one and its not as quick as other 172s plus sounds like a feckin diesel on cold startup!

I read this ages ago and ignored it...

 

[.:xTreme:.]

Rich, do you use Optimax??

 

[Lee]

I ran mine in as recommended by the manual and have run it on Optimax from day one. Its only had 3 tanks of none Optimax in 12k miles. Why would people want to use anything other than Optimax anyway, Renault recommend 98 ron fuel for optimal running, so that leaves you with no other choice.

 

[Griff]

All I can add is that I followed the guide lines strickly with my 172 but ragged it from day 1 with my Cup. The Cup sounds better and doesnt feel as rough.

Well thats cleared that up, looks like ill be coming to a shell station near me soon !!!!

 

[Lee]

There is a sticker on the inside of the filler cap which says 98 ron recommended.

 

[.:xTreme:.]

Oh, well I aint taken delivery yet thats the first I heard of it being 98 Ron recommended

 

[Lee]

I think theres a little chart in the manul too which states that normal unleaded is fine for but optimal running 98 ron is recommended. Stops the engine pinking apparently.

How long have you go left to wait?

 

[.:xTreme:.]

Monday m8 Im fecking chomping at the bit!!

 

[Jim172CUP]

its all a ploy to get them to sell more expensive petrol. Ive tried them all and it makes no difference at all.

 

[Lee]

I take it you have booked the day off work. I hope the roads are dry for you too mate, everytime Ive had a new car its chucked it down.

 

[.:xTreme:.]

LeeM your website is cool m8............. didnt know it exsisted till I ran a search on you

 

[Lee]

lol, thanks. A bit lacking in content but Ill continue to add to it as I go along.

 

[jon_r]

stalking, LOL!! IMO running the car in is essential mate. Just take it easy. Less than 4k for 650 miles etc etc. Its well worth it.

[.:xTreme:.]

K thanx for the help fellas. btw Lee I cant really see the finish line of that race you had, who won??

 

[Lee]

He beat me by 0.010 of a second mate. You can just make the times out on the boards I think.

 

[D-CUP]

Ive been driving normally. Not thrashing it but not pottering about either. Ive gone over 4000rpm a few times. Its still quicker than most cars without trying.

 

[RT_beast]

just wondering..what happens when an engine is pinking?

 

[Griff]

pre-detonation of the fuel

 

[Jim172CUP]

thought the cup had a knock sensor and therefore it wouldnt pink?

Yeah, pretty much all of the time...

It does and it shouldnt

 

[edde]

The 172 and Cup have a knock sensor but maybe it isnt working or isnt reacting fast enough to stop the pinging.

a lad at work thrashed its nuts off from new... absolutly made it sceam and its never had a fault and seems to run faster.
