Title: How to avoid carbon build up
Post by: Chchgti35 on September 09, 2017, 06:49:25 pm
Hi there, have just purchased 2012 NZ new GTI 35 edition, what's the best way to avoid carbon build up ? Will be running it on minimum 95 octane, will periodic high revs be helpful and proper warm up?

98 + smashing it once per day does the job (but dunno the specifics, like what revs you have to get up to and how long to hold it for)

I generally do this several times a week just to hear my exhaust talk but it's only doing 5000rpm for maybe 2-3 seconds, unsure if its enough time to clean the carbon out - rest of the time its in drove mode doing 2000rpm

I don't think the octane is a big issue. but 98 technically will be a bit cleaner than 95 plus you get slightly more mileage and power
But don't put anything less than 95 in the GTI unless you want problems

Yup same here I use nothing but 98 , We tend to go on a good drive at least once a month.

Honest Answer is to buy a car that doesn't use Direct Injection.

Thanks folks, no worries on the sub 95 octane score we use this on all of our cars. No fuel additives recommended or is this a No No?

Exactly this. Because the car is direct in injection, there is no fuel wash in the intake manifold. There is no way to prevent carbon build up over time. It's just part of the deal with DI

There are ways to assist minimizing the build up, but still not preventive.
Catch can's don't really help all that much.

Look at removing the PCV system entirely, not a PCV block off plate either
If you feel that way inclined.

Also you will note with 95 octane, the car will be running higher than usual knock. Due to the lower octane rating.]
send me a PM if you need anymore assistance etc.

Thanks,  have just filled the tank with 98 and was surprised to see the consumption drop markedly in a short time, leading me to believe the tank we just went through ex Dealership was most likely 91 octane. No great surprises there as they obviously would have no long term investment in the health of the engine. Love the sport mode itís a dramatic mood change.

91? damn that, you'd get engine knock straight away

Only if you were driving with your foot flat every where, oh wait were talking about a DSG Golf Driver.. that all they seem to know how to do.
