2.5 VW 5 cylinder in VW GTI race car.

[oliver88]

We are racing a VW GTI with a 2.5 cylinder motor...the motor is stock and we are using M1 0w40 on a 8-10 hour oil change interval. The car is used in Champ Car endurance races, some are 8 hours each. Curios as to the boards thoughts on this oil choice. We do not have a catalytic converter on the car and we do have a catch can/cranckcase ventilation system. Any suggestions or keep using the Mobil 1 0w40 ?

 

[fantastic]

which one? Mobil has like 3-4 0w-40's.

The first 5 cylinder motor I had was in a 1984 Audi GT. Beautiful sounding smooth motor. Plenty of power too with the CSI fuel injection. Design was so good on that car that at 100mph with the sunroof open and the front windows down you could still talk to each other normally. I never had another car like. My 944 Porsche was pretty close though.

When did VW put the I-5 engine in their GTI? Did you do an engine swap or hop up a normal Golf? Just curious.

There are always suggestions but there's nothing inherently wrong with using what you're familiar with and is appropriate for the application. M1 0w40 (FS) for the win!

That oil is fine. Buddy tracks a MK5 Jetta with the 2.5. V. durable engines. I wouldn't change what you are using.

Two and a half cylinders?

Seriously, which 5-cylinder? NA (Golf Mk.5 and Jetta) or TFSI (RS3 8P/8V and TT-RS 8J/8S)?


On a side note, VW offered Golf GTI Mk.4 with 10 valve and 20 valve 2.3 VR5 engines next to 1.8T versions for European markets.

I suggest you check the virgin oil analyses spreadsheet in the VOA subsection. Look for a high high temperature/high shear (HTHS) number of at least 3.5. Higher HTHS typically means better protection.

I thought MK5 did offer teh 2.5 in the GTI before they did the turbo 2.0?

I’d consider the M1 X2 5W-50 depending on your oil temperatures.

Not for the GTI.

- Mk.5 Rabbit (Golf) >> naturally aspitated 2.5 inline 5 (manual or slush box)
- Mk.5 GTI >> 2.0 TFSI (EA113 and from 2008 up EA888 1G); manual or DSG

NA markets only.

That must be a little monster if it has the RS3 2.5L engine shoehorned in there. Pics please.


Oh, and the M1 FS 0W-40 Euro (presumably what you're using) is just plain fine.

Assuming it's a A40 Porsche 0w40 then that's a fantastic choice for your race car.

We swapped it 2 years ago.

It was a Jetta motor

M1 0w40 Euro

M1 0w40 Euro

FYI there are x2 different Mobil European 0w-40's.

Should be a solid track motor.

0w40 sounds reasonable, Mobil 1 is solid. What oil temps are you running?

220 usually...240 last race on July 21 in Pittsburgh...ambient temps were up there and we were really running the motor hard, redline on every shift. Got 2nd in class though !!
