There is virtually no difference. The home heating oil will lack the antigel additives so you would need to add them for winter use. Heating oil is dyed since there is no road tax paid on it. Getting caught using it will be very expensive. That said, I would find it extremely unlikely that they will test a MB. Mostly trucks, commercial vehicles get tested during routine stops/weigh stations, etc. Likely your 97 would be fine on it. My buddy's dad in high school had an extra large oil tank for the house in his garage. He fueled all his cars this way back in the mid-80's and never had any problem or got caught. RT
