Quote from MariusMM :

The oil gadget in RAC next to speedometer keeps going up/down when I accelerate?

I think Scawen mentioned that its meant to be like that. Oil pressure goes up with the rpm.

Here we go, it was introduced in Z20;

It's normal, It even does the same in the "NASCAR 2003 Season" game by Papyrus. If the engine blows, the pressure is at 0, when revs are high, pressure is high.

i thought it was turbo

Turbo is on the other side. But, it doesnt work on all cars only RAC from what I've tested.

We have a Chevy Tahoe that also does this. When you rev past 4k the oil gauge starts moving. When I get back in the truck I'll take a picture of this.

Guys, dont whine. Its a feature and not a bug
