How do I look after my Diesel?

**Greg Roles** · 16-03-2015, 06:48 AM

Yeah, I'm over two stroke oil discussions too. Just use it or don't. Next.

A diesel is no different, but fuel is probably the biggest thing nowadays. I would suggest using BP or Caltex, as they add cleaners to help keep injectors in top shape, but I'm sure Shell is fine too. I avoid all the no name and cheap diesels utterly.

Supercheap has Moreys Diesel Smoke killer, which is probably just two stroke oil, but it's all the additive you'd ever need.

A catch can is a great idea, but is a DIY and does take a bit of tinkering ability.

A tune on a TDI is a massive jump, any of the decent brands will give you a fun result. If you have warranty and its a late model, you have to consider the fact the dealer automatically detects OBD flash tunes and keeps that on file. There are other methods around that.

Drive it normally, and try and get a feel for when it may be regenning the DPF, usually a raised idle is the only indication in the latest cars. At that time a 10km long drive is smart, but the idea of doing a random highway drive will do little, unless you only do short inner city trips.

Welcome to the joy of oily hands at the diesel pump, and just make sure you never zone out and put petrol in it. Much badness.

Haha I assume you've put petrol in it once?

No, but people do. It's a terminal situation for your Pistons.

As GolfVII said. Love it first, then cane it.

My DPF sent the car into limp mode in the first 1200km. The service manager in no uncertain terms told me to thrash it and have done so ever since.

I'm almost up to 210,000km in 7 years, no DPF failure and the clutch is only wearing out now. Just gun it when you can and try not to drive it off boost, which in DSG is almost impossible, and it will be apples.

I've only ever used BP in mine and serviced on the interval. Intakes do SFA but make you sound like Darth Vader breathing through a megaphone.

I have no issues with caning it

Absolutely phenomenal DPF lifespan, you are sure doing something right!

You'd think EGR contamination issues would have popped up.

**Greg Roles** · 17-03-2015, 09:47 AM

Anything soot such as EGR will regenerate. Oil ash is the killer, so Ben obviously has limited oil entering his engine via blow by, PCV, turbo seals etc. He may also be the luckiest dude on the planet!
