Replying to: unknown (Nov 08, 2006 3:00 am) I work in Northern Canada, for one of Canada's largest producers of Synthetic Crude Oil. (450,000BPD) Synthetic oil will not hurt your car from new. As you mentioned it is a factory fill for many cars. Where I live we see -45C temps and regular regular oil just won't stay fluid. Synthetic oil is out of the ground just like what you'll here people call Dino oil. The difference is how it is hydrotreated (removal of sulfur and nitrogen as Hydrogen sulphide gas and ammonia respectively and turning Hydrogen double bonds, into single bonds removing diolefins & olefins which are the waxes in your oil]. The process of upgrading the synthetic oil, also equals a very consistant molecular weight. Which is why it flows well in cold and doesn't break down in heat. They do not need to add as many additives to the oil to make it perform in minus degrees or plus degrees. Non-synthetic oil may have some molecules that are a weight of 1 and some that are a weight of 100, but the average comes to 5 (this differece increases the need for additives to make the oil exibit the desired weight properties, pour point, flash point, froc point etc...). Where in synt the weight comes very close to 5 across the different cut points of the oil > less need for additives I know that is alot of detail, but in short Synthetic oil and "regular oil" can come from the same base stock, the difference is in the upgrading. Where I work we extract the oil from sand (oil sand). The difference is how it is treated before it gets to you. Hope that helps, Netwon |

Replying to: rpfingsten (Nov 09, 2006 2:51 am) but I have been using it over 25 years in all my vehicles, they have a broader range of oils,they make their own oil and air filters.I am a dealer but mainly to get the oil easier,will get to anyone who wants it for my cost.they do not have a filter for the av yet so I have been using the toyota one.I will probably change the filter at around the 4 or 5k life of the oil and go from there.(will check color and maybe take a oil sample).

Replying to: oilcan2 (Nov 09, 2006 10:45 am) Bottom line: Use Amsoil or Mobil 1, you are 450% better off then conventional oil if you drive with heavy loads, extream heat conditions or cold conditions. (Or just like me, like to have the peace of mind knowing that your 25k+ baby is looked after to the best of your ability. Would you agree? Netwon

A couple of weeks ago, the MAINT REQ'D light came on to indicate the need for an oil change. I thought I could turn it off by holding down the trip odometer button while the ignition was on. Didn't work and I still don't know how to disable that message. Anyone have a suggestion? Dandydon

Have a 06 Avalon and did my first oil change a month or so ago thanks to the instructions I found here on this site. I've used AMSOIL for about 15 years now thanks to a tip from a guy at work. Ran a 86 Camry on it 'til I gave it away, still running but not much power, at 220 thousand. Ran a 96 Camry on it from new til 100 thousand, my daughter has it now and still running AMSOIL. Also use it in a 94 Civic and a 87 Nissan pkup. Last but not least I used it in a 79 Chevy pkup. Instructions I got from my friend that I follow is to add 1 quart instead of regular oil at an oil change then use just AMSOIL at the next. Per AMSOIL I run 6 months, change my filter only, then at 1 year change oil and filter. One of the things that made me a fan - The Chevy truck leaked from every gasket and the main shaft seal after changing to AMSOIL, heard it would do that on an old engine but I was younger and more energetic then! Changed all the seals and then ran the truck for a year when it blew a head gasket, ( inline 6's do that). Decided to tear it down and do rings and bearings while getting the head ground. Inside the engine I found that everywhere oil was sprayed under pressure the metal was as clean as new with NO sludge at all, other places had quite a bit of buildup, these were places that did not have oil sprayed at them. Truck was sold at 185 thousand due to body rust. The engine went into a delivery truck and had daily use for about 5 years after - not sure what oil was used. Engine maint. lite I cleared by following the owners manual. |
