[QUOTE="JAJ, post: 11808058, member: 131874"] An engineer in any field deals with budgets in everything they do. There are energy budgets, thermal budgets, weight budgets and a whole plethora of limits that a design has to stay within. Just because financial budgets are based on educated guesses of what customers will pay for the product, and they're calculated by accountants who are not engineers doesn't mean they're any different. If you read the article about the Coyote engine development, they talk about all kinds of budgets and how they traded off one limit against another the whole way through. Ladies and gentlemen, that relentless tradeoff analysis IS the CORE of the product design and engineering process. In the long running debate about engine oil viscosity, some people believe that Ford made a tradeoff between oil viscosity and engine life, and that belief has been amplified to the level of a conspiracy. While there are a number of strongly held opinions on the matter, I'm not aware of any hard evidence that the use of 5w-20 oil [U]where it is recommended by Ford [/U]has led to any bad outcomes. That could be because I'm misinformed, but I have looked for some time for these kinds of issues and frankly they haven't presented themselves. Where are all the demolished engines that 5w-20 has caused? [/QUOTE]
