Diesel Smoking Black? It Shouldn't.
Your diesel vehicle shouldn’t smoke black. If it does, something is wrong, and it would be wise to get it checked out as soon as possible.
If you have an older vehicle with a few more miles on it, it could simply be that it has accumulated a lot of combustion products in critical areas; resulting in compromised engine functionality. Keep in mind that diesel engines run longer than their gas counterparts and diesel is a crude fuel, with no detergents from the refinery. These two factors cause diesel engines to be more prone to engine deposits.
The fix, in most cases, is to add a fuel additive when you fill up your diesel vehicle, and do it on a regular basis. We recommend Stanadyne as a fuel additive, as our experience has show it to be the most effective. Ask your Service Advisor next time you’re in the shop about Stanadyne and it’s potential benefits for your vehicle.
Remember, your diesel should not be belching black smoke. This is a red flag and needs to addressed ASAP! Give AG a call today if you're experiencing this issue. 503-253-1747
