If you are not comfortable with looking at the current times ( clock ) when folks signed up between the two posts as legit order, I would put my vote in for a new post next Monday.
October 2, 2016 at 8:32 am #1642690Some confusion has arisen recently regarding the use of the word “synthetic.” Several petrochemical companies have developed processes involving catalytic conversion of crude oil base stock under high pressures and temperatures in the presence of hydrogen to form very high-quality mineral lubricants. These oils, which are known as API Group III, are so highly refined that their properties almost match that of the Group IV synthetics. They are so close in fact that the U.S. court system sided with a manufacturer of these Group III “synthetics” when a lawsuit was brought up for false advertising. Even though these Group III base oils are derived from crude oil, they can now legally, from a marketing standpoint, call them synthetic
October 2, 2016 at 8:26 am #1642687October 2, 2016 at 8:17 am #1642685Most engine oils are now formulated with Group II (hydrotreated) or a mixture of Group I (conventional mineral oil) and Group II base oils to meet the latest API gasoline and diesel performance designations.
Because Group III and Group IV (PAO) base oils are both considered synthetics (since 1999), any oil labeled as a full synthetic would contain either Group III or PAO, or both. Any oil that is labeled as a partial synthetic, semi-synthetic or synthetic blend would contain Group I or Group II (mineral oil) plus some amount of Group III oil or PAO (synthetic). Keep in mind that there is no minimum quantity of synthetic base oil required in order to call a blend a semi-synthetic lubricant.
There are also no designations for end users to know what specific base oils the oil formulator has used, so your question is a bit academic in nature. We would never be able to tell if we were purchasing a Group III engine oil vs. a Group IV (PAO) engine oil.
However, from an academic point of view, I would expect the cleaning ability of a Group III and a PAO to be similar (generally poor). Again, academically, I would expect less risk of seal issues, etc., when switching from a Group III oil (as opposed to a Group I oil) to a PAO, as the Group III oil and PAO are chemically similar.
Ester synthetics have a higher degree of solvency than Group II, III or PAO base oils. This means they will dissolve additives and deposits more readily and may cause some seals to swell slightly. They also can remove some paints. These characteristics (other than paint removal) can be beneficial, so some oil formulators will add small amounts of ester base oils into their synthetic (Group III and PAO) formulations to improve these properties.
The reason for this post is to let readers know that their is a huge variance in the way manufacturers formulate and blend automotive oils. Your best indicator on the amount of ” true synthetic” base oil that is in a quart of oil will be apparent by its cost. Group IV and V base oils are far more expensive then group I II and III ( mineral oils ). Lots of oils being marketed as full synthetic without using a Drop of group IV or V.

January 22, 2013 at 3:07 pm #1133514Years ago I started buying Scheels Guide series Rods. They have lifetime warranty. I bought 8. Since then I have never had to purchase another rod. They match the quality and performance of the top St Croix Rods and if you break one you just bring it in the store and they replace it on the spot. As for Spinning reels. Flueger is about the best I have ever found. For around $50.00 for the president series you cant find a better reel for the money. Unfortunately in the reel industry most of the technology is invested in Bait casters leaving most spinning reels left in the use and throw away category. Just my 2 cents. Hope it helps.

October 19, 2012 at 2:41 pm #1106276The summer blend evaporates more readily in warm temperatures so states convert over to a ” winter Blend” somewhere around the 30th of October each year. Essentially it is a less quality fuel due to the way it is refined and would evaporate more quickly than the summer blend on a warm day. It is also cheaper to refine allowing more volume into the distribution stream thus lowering prices.
October 19, 2012 at 2:31 pm #1106272Engine Oil manufacturers spend billions of dollars on research and development to manufacture and design Oils that meet the API regulations of an automobile manufacturer. There are strict guidelines in what can go into an engine oil blend to maintain warranty and emission standards. Lets take for instance the new API SN specification that is the latest for 2011 and newer vehicles. The API will not approve an engine oil unless the additive chemistry” muscle” of the oil is cut back as much at 30% due to its effects on the converter. In essence the new engine oils have been dumbed down to meet regualtion. By putting a completely foriegn material into a certified oil you can run into all sorts of challenges and essentially void warranty of a new vehicle and cause harmful effects to an older engine.
My suggestion would be to buy a fully formulated lubricant that has been certified by the API for your year of vehicle.
Royal Purple has a very good beefed up chemistry pack that compensates for the changes in the API certification. I would go with 5w-30 or 10w-30 HPS. Fully synthetic, meets manufacturer specs and will give you vast improvements in engine performance from past parasitic loss due to wear and tear.
Just a suggestion. Good luck with your research

October 25, 2010 at 6:04 pm #906007Unfortunately, Bret has proved to be no better as a moral human than the likes of tiger woods. These guys lose total perspective of their obligation as a role model. I respect Favre as an awesome quarterback but his personal failure has created a very poor outlook on him as a family man and ethical Role model. He will go down for his behavior. None of these high paid entertainers are above the law!!!
