Or at all?I‘ve got a ‘93 Lincoln Town car (134k miles) and a ‘92 Dodge Shadow 2.2l 4cyl (38k miles - not a typo). I‘m about to change the oil in both of these cars and I‘ll be using valvoline high-mileage in both (seems to help with brittle seals on the Dodge). I‘ve been thinking about oil and fuel additives, like Lucas. Is the stuff ever worth it or is it snake oil? Experiences? Thanks in advance.
I'm a huge fan of Seafoam for my older motorbikes and car. Keeps water out of gas and dissolves a lot of the gunk in fuel lines, carb, etc. Costs about 8 bucks US but is worth it in my opinion.
It is best to use nothing but clean, new oil and keep it clean by changing it often. There are hundreds of additives that make all sorts of claims, but in all my years fixing what people do to their cars I have deduced that most all of them are a waste of money. No engine is designed to use any of them. Just use a high quality oil, as well as a good filter, and good parts in any repair you make and you will get the best results.
No auto manufactures recommend these additives. No repair manuals specify them. Only the people selling them tout them. That's your clue.
