Reply to "Toyota Engine Oil Sludge/Failure"

Charlene, I tend to believe your side of the story. Toyota, faced with a potentially huge recall could very well be trying to avoid its responsibilities. People tend to be very loyal to companies they believe to be good to them and I think Toyota, now swimming in profit, might be getting a bit arrogant and taking advantage of this. We'll see.

Let me throw in this consideration. There has been some contention above that if a synthetic oil is used, no sludge will develop and you have disagreed. This is a classic case of the two sides not defining what they are discussing.

IF the lubricant is a true synthetic lubricant such as SynLube, Redline or Amsoil, sludge will not be an issue. These are true synthetic lubes. They have a much greater ability to tolerate heat and to release heat once away from the heat source. I don't think you will find any case of sludge when these oils are used.

Other oils, marketed as 'synthetics' like Castrol Syntec and others by Pennzoil and Quaker State to name a few are petroleum products based on Group III base oil. In my view, the marketing of these products amounts to a hoax where the marketers make a large profit selling the consumer something different than he thinks he's buying. People who bought these oils may indeed be among those you have heard from.

very true Houckster, not all "synthetics" are synthetic. Mobil lost that case years ago to Castrol.

Get true PAO synthetic oil, do your proper maintenance, drive your car further than the grocery store and faster than 60Kmh on occasion and you will not have sludge problems.
