Here is the problem: you have a vintage car that has been passed down to you, or it is one you bought and cannot wait to restore. It runs well and drives fine considering it has its original motor. There is just one minor problem. Every time you put the key in the ignition and turn it, the engine starts smoking like last vacation’s beach bonfire.
You could buy an engine rebuild kit but that can run you close to a few thousand dollars depending on the car you own. Maybe you have heard of engine oil additives and wondered if you can solve the problem with one of these stop smoke products. So, can they help?
If you look at what some classic car owners have to say online, they will tell you that many of these products are not going to. That is, of course, if you are adding synthetic products to your engine. First, a few special tricks for you to try.
If you purchased the car yourself and it had been sitting around unused for a while it is possible the problem can be driven off. If you go at least 100 miles with your new, old beauty, she might stop burning smoke. It could be the engine just needs to clear itself from sitting unused for so long.
If that does not work, you have to be careful because you do not want to burn the engine out. With the scenario above many classic car owners assume that the next logical move is to add engine oil. The problem with doing this is that today’s engine oils are designed for high mileage cars. They burn the oil off at higher temperatures. This would make your car’s problem worse.
Now is a good time to check for oil leaks. If there are any they will usually appear by the oil pan and the valve covers. You might get away with tightening the bolts to fix the problem. If not, it might be time for new gaskets. Adding bearing seal additive could fix your smoking engine but if not or, if you do not want to chance this fix only to find it does not work for you, there is else you can do.
Drain the oil and change the oil filter first. Start using single-weight heavy grade oil. Ask your mechanic for more details as they pertain to your individual vehicle and where you live. If you experience extremely cold winters, you will need to adjust the type of oil you use.
One additive that many people claim is a miracle worker which has been used for generations is Marvel Mystery Oil. This helps engines that have been driven hundreds of thousands of miles. Add it during routine oil changes and your engine will stop smoking.
Try the quick fixes described above first. If they do not help, consult your mechanic to determine which additives will correct your car’s problem at a fraction of the cost of rebuilding the engine.
