RDEX Posted November 20, 2002 Share Posted November 20, 2002 Some oil advice please. I have recently done my first oil change on my K series and have decided to use Mobil1. My question is, is it worth or indeed safe to use an oil additive such as STP in conjunction with a synthetic oil such as Mobil1 1? This may seem like overkill. however the cost of such an additive is negligible and it appears to make my other car rev more freely and promises higher protection, and I want to protect my pride and joy as well as possible!! 🤔 Link to comment Share on other sites More sharing options...
KevSull Too Posted November 20, 2002 Share Posted November 20, 2002 Ask yourself one question.... If Mobil could improve their oil by sticking some cheap additive in, don't you think that they would have already done so? Hmmmmm...... 😬You laugh at me because I'm different, I laugh at you because you're all the same. 😬 Link to comment Share on other sites More sharing options...
Simos Posted November 20, 2002 Share Posted November 20, 2002 Do not use oil additives. Any of this PTFE etc reduces friction in the engine stuff is bollux. Link to comment Share on other sites More sharing options...

fordy Posted November 20, 2002 Share Posted November 20, 2002 please do not use oil additives in conjunction with engine oils, they are rarely approved by the engine manufacturer. In our case at Ford, I specifically prohibit the use of supplemental oil additives as most do not offer the customer any advantages at all and many are in fact harmful. A properly formulated engine oil will perform the job perfectly, particularly something like Mobil 1. All engine oils are a careful blend of certain performance additives that are designed to work in conjuction with each other. Some oil chemistries are in fact carefully balanced. The addition of supplemental additives can sometimes upset that balance. I have seen cases where this causes certain oil additives to drop out of solution. Basically at best you'll waste your money.

TomBerlin Posted November 21, 2002 Share Posted November 21, 2002 STP is the answer Andy Granitelli found to the question "What do I do to make money with the dregs after all useful products have been refined from crude?" It wasn't an answer to a lubrication problem, but rather a ploy to market an otherwide useless product. Link to comment Share on other sites More sharing options...
Nick Woods Posted November 21, 2002 Share Posted November 21, 2002 The link in Den's posting above is definitely worth a read, its the best debunking of oil additives that I've seen.

puremalt Posted November 22, 2002 Share Posted November 22, 2002 Good article.. A sythetic oil is fine in my experience, but there's loads of threads on this. When is it going to stop raining? Link to comment Share on other sites More sharing options...
