Replying to: drotse (Oct 03, 2008 7:07 am) When you compare the price per mile it is actually less expensive, not to mention the fuel mileage increase and protection to the car !! " What are you talking about? Amsoil is more expensive than Mobil 1 0W40 that I use. I change oil each 5K miles. Do you suggest I keep Amsoil longer in 1.8T than maximum recommended by VW for oils that meet VW 502.00, 503.01? Krzys PS My car has 95K miles. |

OK here is the skinny on AMsoil. Just letting you know my personnal experience. Look up the Amsoil web site Oh here is the link http://www.amsoil.com/ , read and become informed. I am not going to tell you to extend past the manufaturer interval but I owned three Nissan pickups (not turbo). I drove them 3800 to 4000 miles a week as a courier. I changed the oil at 25,000 to 30,000 miles. I ran one 670,000 the other two about 375,000 a piece. NEVER ANY ENGINE WEAR PROBLEMS ! AS a matter of fact I blew a head gasket on the 670 truck at 310,000. THe cylinders had no score marks, the timing cain was in good enough shape that the sprockets still had their hone marks on both sides of the teeth. I was using the amsoil 1mc. filters(important!). I have a 2003 freightliner Sprinter with the turbo diesel 117,000. I use the Amsoil 15W-40 diesel in it and change it at 20,000 weither I have to or not. Now here is the thing. When I went from oem oil to Amsoil at 10,000 in the Sprinter I gained right at 10% MPG. In the nissans I experienced the same increase over using a Castrol GTX with a Teflon treatment added. Now going from Moble 1 to Amsoil might not give you that much of a boost but Ithink that if you relly want to learn more I would get in touch with the folks at Amsoil and Check it out. One thing you must also do is use the fine 1mc. fiters,remember that normal oil filters are usually 10mc. That makes a big difference. I don't know if Moble1 can be used with 1mc. filters. If it can then do it and get great protection. I have a friend that has a 2000 Passat. I flushed hie engine, put in the Amsoil with the 1mc. filter and he now has 160,000 on it NO TROUBLES( the change was at 23,000 miles). Now ironically reding alot of these threads on this forum it seems people are haveing more troubles with this engine after they switch oil. The reason is the new oil is cleaning andloosen up crap and the pickup screen is close to the pan. DO A GOOOOD FLUSH. The dealer in Wisconsin that has done the work on my son's car was gracious enough to email me the protocol that VW has for this problem hopefully they followed it to the letter. |

| I just called to the Mobil1 tech support line and they said the Mobil1 can not be filtered any finer than the standard 10mc. filters. So Amsoil can go down to 1mc. so it will remove a whole lot more stuff from the oil so when comparing the two oils take that into account when comparing protection and price. | |

More on filters. Amsoil can be filtered down to .1mc.. At that point the by-pass filter will keep the oil so clean that with regular testing, to determine the quality of protection, you might not even have to change the oil for 100,000. And that is typical of over the road diesel truckers experience. Now who wants to scream at me when I say that Amsoil is superior to Mobil1. |

...but this is getting off the track of Passat sludging. You can't run a VW Passat 1.8T 20 or 30,000 miles with an oil change. Not without jeopardizing the warranty and jeopardizing the longevity of the engine. I wouldn't compare low-revving over the road diesel engines with sumps that hold gallons of oil to a forced induction gasoline engine that barely hold 1 gallon. Look. We get it. You love Amsoil. Maybe you're even a dealer to get a price on the stuff in their pyramid scheme. But you're doing a diservice to other readers here by hinting at extended oils changes being appropriate for a very hot running, small sumped, gasoline forced induction engine. Anyone who does is making a leap of faith. Your son's case of doing 3,000 mile oil changes and getting warranty coverage on a sludged engine is one thing. But it's another to lead people on, some of whom aren't familiar enough with this car to consider the consequences. I can tell you this...the web is full of stories of people who couldn't get their sludged engines covered because they couldn't supply full documentation of all oil changes within a 5,000 mile interval. |

And your point is ? You can if you do the above. I have a freind that has and at 160,000 miles he has no problems. Now there you are. You are talking about sludge problems. Why? If you do your oil changes and use good oil you will have no problems. Yes the engine has a propencity to sludge up but if you do it right(oil) there is no reason to predisposition yourself to have to cry.

Well in case of VW it is oil meeting VW spec, not claiming to meet. Krzys PS Go to your amsoil data and check what they have to say about Subaru turbocharged engines. If I am not mistaken they recommend 3750 miles OCI just like Subaru does. |
