What if I added too much Sea Foam to my Jaguar’s motor oil? [SOLVED]
I am a very happy user of Sea Foam in my gas. I drive a 4.0L V8 2000 Jaguar XK8. But this time I decided to add it to my oil before changing it. Unfortunately, I got mixed up and I put twice as much Sea Foam as recommended (one full can to a 7qt crankcase). I have not started the engine yet in fear of having made my oil too thin or to prevent any other problem. What do you recommend? I think I can still add another quarter of a heavier oil to compensate the viscosity, use it for a 100 miles to get the systems cleaned and then change the oil.
Hi Alex. Adding 16 ounces to 7 quarts of oil doesn’t require you to do anything like add more oil or a heavier viscosity. Just drive 100 miles and have your oil changed. No worries!
I have a 2003 Buick Park Ave. I made the mistake by adding the whole bottle now my car is jerking. I need advice what to do. My car feels terrible.
Hi Markilya,
Here’s what our tech rep (a former mechanic of 20 years) said about your question: “First, go ahead and change the oil. However, I don’t see how 16-20 ounces of Sea Foam in the oil crankcase would cause a bad running or misfire situation. If your Buick keeps running poorly after the engine oil has been changed, I’d get it properly diagnosed by an ASE Certified Repair Facility.”
Let us know how it goes!
