Actually there are two normally used filter media: Cellulose (paper-cheaper), and fiberglass (normally better and more expensive). The reason fiberglass is superior to the paper ones is that the strands of glass are a uniform thickness and filter more consistantly. They have more pockets (pores) than paper which has only nonuniform holes in the paper. In addition fiberglass media lasts longer. This is measured by multipass tests which measure the ratio of particles trapped at specified particle sizes. I know for a fact that Mobil 1 filters have fiberglass media. From previous discussions on these boards Pure one, Amzoil, and Delco Ultraguard are also of this type. I use the Mobil 1. Later |

I wonder if somebody can clear this up for me. The oil study page calls the Pure One filter element synthetic.

On the other hand the Purolator's own site doesn't mention that term anywhere in its product description.
http://www.pureoil.com/featuresandbenefits.htm
Therefore I conclude that its element is not synthetic (a blend maybe). BTW I use the Motorcraft filter - Pure One media at the half price. |

| think it is a paper element with these performance specifications. It's almost certainly fiberglass media. (synthetic-I guess although I never heard it called that) | |

After visiting this discussion some time ago, I switched our '96 Toyota Camry and our '99 SVT Contour to this product. Also began using the Pure One filter. I was using Valveolene fossil in the Camry and the synthetic "blend" for the Contour. The new Mobile 1 works great! I think that the SVT has benefited the most from this change. Both use 5W30. |

I still feel using Synthetic oil and $5 oil filters are waste of money, but for respect for all of you Synthetic oil users, on my next oil change, I will try Mobile I in my '96 Camry V-6, and will report on how I like it, and whether the gas mileage or car drivebility is any better. The difference will be $20. I still hate to let the car go 7K before oil changes. I do mostly highway driving 70 miles everyday. By the way based on 150K miles on a car, and 3K vs. 7k oil changes, the cost difference will be about $310. |

I'm not sure how many miles you have on the Camro or how often you have changed oil in the past. I would recommend for the first oil change with the syn you go no more than a 50/50 mix of syn/conventional. I assume you take five quarts. I'd suggest 2 quarts syn. It will get blacker quicker than your conventional oil as it cleans. Change when it gets dark. After a few oil changes you'll be amazed how clean the oil stays. You won't be sorry. Later Al |

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 |
