Is there much of an advantage to paying the extra money for synthetic oil vs conventional? And if so does a name brand make any difference? Store brand synthetic is $5 a quart vs $8 name brand.
Not all engine lubricants sold as synthetic are the same. We can all tell our favorites, but generally speaking, you do get what you pay for in sythetic lubricants. Personally, I like to stick around Amsoil, Mobil 1, Royal Purple, and Red Line. Note that if you don't take advantage of the extended drain intervals, or your engine leaks profusely, or consumes a lot of oil, then the cost may be higher. If you take advantage of the extended drain intervals and your engine holds oil then the price is not only well worth it but the extended life of the engine makes the use of a good synthectic a better deal in the long run. Many people register more horsepower on the dyno when they switch to a quality synthetic. The old belief that synthetic oil leaks is a bunch of hogwash; if you engine leaks oil then the engine has a leak....fix the leak.Is there much of an advantage to paying the extra money for synthetic oil vs conventional?

Your right Paul, it is an old case. When this first came down, only Castrol was using the term for what is basically highly refined conventional oil. All the others where behind Mobil on the complaint. Once the complaint was settled in Castrols favor, it left the door open for others. And, in time they have. Which is why I posted it AGAIN! Everybody and their bother has jumped on this opening. Some have ABUSED the ruling more than others. Castrol is probably now a victim of their own ruling. When Castrol first started marketing Syntec, it was a primarily a group III oil with some group IV to fortify it and bring up its Total Base Number. It probably performed very close to some synthetics overall. Oh well! They made the bed, they can sleep in it.Wow, gn7, that goes waaaay back Good reference material. I used to reference that case in oil threads many years ago. Castrol Syntec used to be a true synthetic when it first came out, then the makers of that lubricant found a way to restructure petroleum-based modelcules so as to give them performance characteristics (film strength, viscosity stability, etc) like that of the synthetic stock competitors. They made no public announcement of their change (on the bottle) and that intiated the court case. Castrol maintained and provided documentation that their product was indeed changed in the lab and perfomed like synthetic based stock lubricants and thereby won the case against them. And I was pissed as well.
Brad-Penn isn't exempt from the confusion any longer. Use to be Brad Penn meant 30, 40, 50 and 70 wt. Period. Now add to those, full synthetic(FSGF), Synthetic Blend, Partial Synthetic(explain that difference!!!!), Premium Penn Grade and Superior Fuel Saving. Yes those are all now Brad Penn oils. I'll let you guess which is good and which has no business in a lawn mower.I have been using Brad Penn, it came recommended from Fowler Engines, who build tractor pull stuff, that really takes a beating.
Yes! Some good oils have expensive add packs to them such as Zink and anti foaming agents. We use Lucas.Is there much of an advantage to paying the extra money for synthetic oil vs conventional? And if so does a name brand make any difference? Store brand synthetic is $5 a quart vs $8 name brand.
Too answer your question MS, yes there is an advantage. Like Boostpower said, good additive packages cost money. And like I posted above, the name brand might actually be a synthetic oil if you shop right. Chances are, the store brand is not what I refer to as a synthetic, as Lakes Only mentioned.Yes!

Come on Steve, you know better than to ask that question. Only thing wrong is the price and the availbility. If you have no trouble with either, even if its used, its better than most of the stuff you can by at Pep Boys. Every quart I ever ran in my boat went thru my car before it went to the recycler.Anything wrong with Torco 20/50?
