Hi! I also have '99 Passat, but my wise drives it mostly around the town, short distances so in two years she put only 20K miles. So far the car was serviced by the dealer |
|
| you are saying the car is abused? A car should be able to handle 20 K in stop and go for two years unless you did not change oil in that time. If it doesn't use oil than it is probably not abused. Switching to syn in my opinion is the right move for longer engine life. If you want to be conservative change at 500 miles with a good oil filter (Amzoil, Mobile 1, Delco Ultraguard, Pure One) My $.02 | |

On my 3.8 Buick (1995), if I put a FRAM on, I hear valvetrain noise as if if it was 2 quarts low so, as I have done in the past with my other GM products, I stick with AC-Delco for my oil filters. They've given me satisfaction for barely 40-50 cents more (CDN) per filter than the Fram... Dunno about other car brands but I've always heard than GM cars were quite fussy about their oil filters... |

| product in the driveway for 40 years. Mostly Chevs. Used all kinds with no problems. If you like Delco, go with the Ultraguard otherwise the Mobil 1, Pure one, Amsoil as has been mentioned here many times. | |

The AC Delco filters are actually less than the Frams at Walmart (about 11 cents I think), so why use an inferior product when you it actually costs a little more? The Motorcrafts are also about the same, although I'm not sure if they're a little more or a little less. I plan on trying the Motorcrafts next because I found out that they use a Purolator Pure One filter element in a Purolator Premium Plus case, and they're less than $3 at Walmart also. After all the evidence against Fram, and the fact that they aren't any cheaper than the AC DElcos and Motorcrafts, why would anyone continue using Fram? Probably the same people that bought the Chevy Vegas in the 70s. Ken |

| I went to Advance Auto Parts yesterday, formerly known as Parts America. Anyways, they had the Purolator Pure One on sale for $4.99 each. Regularly $5.99 each. I bought 4 for each of our cars. I have been using Bosch filters at Autozone for $4.99 each. Same price and I figure the Pure One is better since the filter elements are synthetic. | |
| It's element is not synthetic. | |
| ahh. Ooops, I thought it was. I'll still keep it for $5 a piece. | |
|
Ok, I guess I have to bite on this one. Can anyone offer a logical reason why a synthetic element is superior than say an...errr... "all natural" one? What is it about "synthetic" that makes it better than the alternative? |
|

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 |
