uaesolidsnake Posted March 27, 2006 Author Share Posted March 27, 2006 First of all its my first time to hear about AMSOIL but from the review i can see that its a very good company. but can you put another review to compare oil that is for 3000 mile (5000km) because the AMSOIL review was compareing oil that is for higher milage. Is there any site to review the cars oil? If its there it will be very helpful. Quote Link to comment Share on other sites More sharing options...
humanoid Posted March 28, 2006 Share Posted March 28, 2006 I would suggest logging onto bobistheoilguy.com. It's more than you would care to know about oil and anything related to it. Just my 2 cents, but Amsoil makes one of the best synthetic motor oils in the world. Quote Link to comment Share on other sites More sharing options...
stevelaw Posted March 30, 2006 Share Posted March 30, 2006 I like Mobil 1's formula, but I have been using a semi synthetic from Mobil: Mobil Clean 7500. The gas mileage improved a bit over conventional oil. Quote Link to comment Share on other sites More sharing options...
joehyundai Posted March 31, 2006 Share Posted March 31, 2006 AI have to agree with using the Mobil 1, but I would not recommend the semi synthetic anything because it only uses a very small percentage of synthetic. Only enough to stabilize the oil a bit. If you want to keep the car for a long time, I recommend using the full synthetic because it doesn't break down as fast, suspends more particles, and leaves no deposits. Even with hard use it's ok to leave in for 5-8K. Just make sure you're not using a cheap (fram) oil filter. The Toyota filters are best to use. If you don't like using synthetic, one of the best mineral based oils to use is Texaco Havoline. It has the least amount of Paraffin. All Pennsylvania oils are high in Paraffin and will leave deposits. Quote Link to comment Share on other sites More sharing options...
stevelaw Posted April 5, 2006 Share Posted April 5, 2006 All Pennsylvania oils are high in Paraffin and will leave deposits. My brother in law worked as a Ford salesman for a long time. The older folks that would buy Mercury Grand Marquis, Crown Vickies and the like would tend to get their oil changed at the dealership. For some reason, at that time, the Blue Oval camp was using Quaker State in the cars. Well, after these cars had 50K or 60K on them, all slow driving by these seasoned citizens, they would develop blue smoke on startup. After pulling the valve covers, there would always be this gloppy waxy goo all over the valve guides--paraffin. It would creep down the valve stems into the combustion chambers after shutting the car off in the evening. Then, in the morning, after starting the car, it would burn and smoke would come out of the tailpipe. Quote Link to comment Share on other sites More sharing options...
