Tech Article: HVO100 in Saabs (and other vehicles)
So, recently I was involved in a debate where the claim was that HVO100 was not approved and not allowed in the diesel engine A20DTx – the diesel engine available for both Saab and Opel.

So, everyone has heard about transmission losses, some claim that the losses are 10-15% on a 2WD car, and I’ve heard about 20-25% on 4WD cars… Well, first, lets think about the values here… Lets say you’re crusing at the motorway, using maybe 20-25hp… then I could accept the losses are 20-25%, meaning your transmission accounts for ~5hp Now imagine you have a 250hp car, lets say you have 20% losses, that alone is 50hp… So lets tune the car now… to 500hp… according to the tuners and people on the forums you would now have 100hp in transmission losses. So, lets do a little sanity check.. Take a Nissan…
