I like many others here suggest you figure out the fuel in the oil issue. Do not waste your money on expensive synthetic oil at this point because you will be changing it again soon because you can NOT get all of the gasoline in the oil out in one oil change. There is one quart trapped in the front of the oil pan plus some in the oil cooler that will not drain.

1. If there is no electric fuel pump installed then replace the mechanical fuel pump. The are cheap. Get one for a 75 OLDS Toronado WITHOUT AIR CONDITIONING. The difference here is you need a pump that has only two ports. (In and out) The pump used on the AC equipped Toronodo has a 3rd port that was attached to a return line to the tanks that you do not have. Before you leave the store look closely at the pump for 2 ports, not 3.

If the mechanical pump has been removed and replaced with an electric one the we need to figure what electric pump was used. The pump you want is a 4 to 6 PSI pump. If they put a higher pressure pump on it, then the pump will over pressure the needle and seat valve in the carb and the excess gas can cause all kinds of running rich problems plus some of the excess fuel can and will end up in the oil.

So change the oil and filter immediately and figure out you fuel system. The mechanical pump (if it is still installed) is located on the lower passenger side of the engine. The lower radiator hose is run in front of it. So find the lower radiator hose and follow it to the engine. If the pump has been removed, then there will be a block off plate held in place with two bolts over the hole where the pump use to be.

There are lots of very knowledgeable GMC people here and all of us are available to help. Most of us are in the USA or Canadian, but we also have a few from other countries like Australia and Europe. I would list them but it is pretty much every one on this forum that will help.

So do not be afraid to ask away.

Welcome
