Hi, trying to find some info on using Heavy diesel oil in a light diesel car. Oil in question is Q8 supertruck ACEA E4/E7 to be used in a 1.9 turbo diesel afla romeo and a 2.0 turbo diesel volvo S40. Reading the spec it might be suited more to the alfa as it has no DPF filter. Any pointers would be much apperiated, i have an endless free supply of Q8 hence the reason of asking.

You had me at endless free supply.

Most light duty diesel cars take a ACEA C3 oil with Sulphated Ash < 0.8 %

The heavy duty diesel E7 has a SA < 2.0 %
Closer would be E9 with SA < 1.0 %

But they all (C3, E7, E9) have a HTHS > 3.5 cP.

My only concern with the high SAPS (high SA) oil is your DPF exhaust filter. No DPF then no worries.
