I've got two vehicles. A 1999 Toyota Sienna that my wife drives and a 2004 Honda Accord V6 that I drive as a sales rep. The van is mostly used for short trips, the Honda almost 600 miles a week. The Toyota has 101K and the Honda 124K. I'm running AutoRX in the Van currently and have put it in both transmissions. I have been using Synthetic in the Van due to the published sludge problems with the Toyota V-6 engine. Based on what I've seen here and on BITOG syhthetic is more likely to sludge than conventional. So, once again, I've outsmarted myself? Bottom line, ditch the synthetic and pick a conventional of the proper weight?
After cleaning and rinse phase you need to go on the Auto-Rx maintenance program and you can use the oil of your choice just follow the instructions. Thank you for using Auto-Rx.
I think it is less likely you will have sludge problems using synthetic oil but there is no guarantee that you won't. Not all synthetics are created equal.
ARX mixes with any oil, so pick one you're happy with. Adding a maintenance dose of ARX to it just makes it better.
If you already have sludge issues go to a non synthetic oil. Engines with sludge problems react negatively to synthetic oil when trying to clean out sludge. The complex additive package in synthetic oil has a polarization effect and holds oil to metal. This is not desirable when fighting sludge. The object is to liquify all contaminants and drive them to the filter. Non synthetic oil works well in achieving this.
O.K., I'll apologize, I just saw my question on the FAQ's. The question I really want to ask is "Have I been sold a bill of goods regarding the benefits of synthetic oil?" There doesn't seem to be a down side to conventional motor oil.
I have always thought you should stay with oil the manufacture recommends I am not sure this answers your question. When purchasing non synthetic oil it is very difficult to find it most Auto Parts sales employees do not have a clue about what type of oil you are talking about.
Group 111 Oils are very close to "True Synthetic" in almost every way. Synthetic oil is primairly used to reduce temperature and extend oil change mileage. It is a good oil "EXCEPT" when you have sludge or seal leaks. If you use Auto-Rx in the maintenace mode I can see no need for costly synthetic oil. Group 111 yes.
No matter whose oil your using if the operating engine parts are dirty'etc your throwing your money away. No oil lubricates through dirt.
