what engine oil for 99' Integra DC4 Gsi

[cbauto]

What oil is so superior?

How much exactly does a good or bad oil effect consumption?

If you think it makes a difference then it must be a real poofteenth and certainly not a genuine selling point for any oil.

I've used FEO, Magnatec 10W-40 semi, Nulon 10W-40 synth (just remembered actually) and currently using Penrite 10W-50 synth with zinc. My fuel economy with the Penrite is currently the best it's ever been since I bought the car in early 2008. So that's five and a half years, and I always drive until my tank light comes on, fill up at the same BP, and calculate my economy per tank.




This is why I went 10W-50, and IMO it's the only good reason to change viscosity. I'm burning about 700-800ml less oil each 5,000KM. Engine is getting on a bit obviously.

Magnatec 5w30, tried it.

was getting 12.5ltr/100km

Changed to usdm full syn mobile1 same viscosity.

instantly 11.5ltr/100km

V6 Vitara.



I would rather use recommended viscosity and top up than use thicker oil.
