I have used both factory and after market filters for 35 years of owning and working on cars and have found no real advantage of either except the factory filters are generally more expensive. I have had great success with standard Purolator and yes Fram filters(used the HP version of the Fram for my high horsepower race cars)and never had any oil related failures. Most of my vehicles went well over 100k and some over 200k using standard store bought filters as mentioned before and good quality dino oil. I have no experience with synthetic oils but do know that the combination I've been using has served me very well for many,many years. I will admit since reading about the cheap construction of Fram's lately and I did experience occasional valve noise at startup with these filters I have ceased using them and the valve noise is history. Only using Purolators now. Just my .02 Lou |

70 miles/day. Even with dino you could extend that period due to the high percentage of highway driving you do. As to the recommendation to start with 50/50. WHY???? You will probably not notice any diff though. And, if your Camry V6 is like mine you cannot really see into the valve cover via the filler hole as there is a plate or metal piece blocking the view. So, may not be able to tell if engine clean to begin with or any affect of the synthetic. As the the above post on filters, well, I have seen a differecne in my oil analysis between the Toyota OEM and the Puralator Pure Ones and Amsoil, both filter better then the OEMs. However, the Toyato air filters seem to filter better then the after market ones, even the oil foam ones! |

First,in the previous post about the Purolator Pure One oil filters, I have not had any analysis done on my oil but have definitely noticed that my oil stays cleaner longer with the Pure Ones. In relation to the Toyota air filters what indicates that they are better than say Frams or Purolators? Is it that they need to be changed more frequently indicating better filtering? Thanks in advance Lou |

Just a conservative approach. We could probably argue about it. As you know syn cleans up really good and if the engine is very dirty it may break so much loose at a time that it could mess up the sender unit (note likely though). He'll still get benefits of syn and be able to go longer on the first change without the oil getting dark real fast, which might freak him out. I'm an old man and when you get there you want to do everything slower and more conservative. Later |

| Toyota air filters. I change once a year. Well, I do oil analyis at least once a year, sometimes twice and over the 9 year life of this car (still going at 130,000) I noticed that the silicon (dirt, well, could be silicon seals as well,especially in the first 20,000 miles. Analysis cannot tell if dirt or silicon seals wearing in) in the analysis (measured as parts per million/ ppm) was lower when I used the Toyota air filters. The others I tried were Puralator and the Amsoil oil foam filters. (foam is fine but a real pain to clean and re-oil and I saw no difference) I did see a drop in the ppm when I kept the same air filter but either the Amsoil or Pure One filters for oil. So, my statement is based solely on my experience with the Toyota and oil analysis. | |
