Yes, the gauges need to be read dead center for accuracy so angling them helps, otherwise the
Caravanner behind you makes comments about it at dinner.

I drove it again today, yet it's only 75F . I did notice one thing. I have the gauges mounted more to the right of the dash center in one of those VDO rubber 3 gauge mounts. I Made a thick plastic plate so I could place the rubber gauge mount on an angle as much as I could . The end of the gauge mount is near the left side of the glove box door .
Point is if I look at the gauges dead center , for instance the temp gauge from the driver's seat reads 180F yet if I look dead center it's between the 120 and 180 mark. So the just below 220 on the hot day was probably closer to 200. That does not mean it was not running hot because the oil light was coming on and the gauges are not 100 % accurate either.
I want to see if I can angle the panel more. It was the only spot I could mount it , doesn't mean I can't improve it a bit. maybe.
