see i would be scared to do that im old school and coming from runnin dino loli'm pretty sure at some point i saw a post of someone running amsoil and doing oil changes once a year (like every 15-20 ish thousand miles) and being pretty happy with it. think they had results of getting the oil tested and stuff too. i'd look for it but i have to get some spacers all packed up to send out heh
I have been using Amsoil High performance 5W30 for a few years now. They do not sell the Ea013 oil filter for our engines any longer. They advise using a Wix 51356 and changing the filter at the manufacturers change interval. I have 6 quarts left and that will provide one more oil change. The Carquest that I bought it from does not sell it any more so I will have to find another way to get it w/o paying an arm and a leg.A direct quote from the products info page:
AMSOIL Signature Series 0W-30 Synthetic Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows:
• Normal Service(3) – Up to 35,000 miles or one year, whichever comes first.
• Severe Service(4) – Up to 17,500 miles or one year, whichever comes first.
• Replace AMSOIL Ea oil filter at the time of oil change up to 25,000 miles or one year, whichever comes first (other brands at standard OEM* intervals).
• In all non-gasoline fueled vehicle applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.
*OEM - Original Equipment Manufacturer
(1) Engines operating under modified conditions are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.
(2) Mechanically sound engines are in good working condition and do not, for example, leak oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.
(3) Personal vehicles frequently traveling greater than 10 miles (16km) at a time and not operating under severe service.
(4) Turbo or supercharged vehicles, commercial or fleet vehicles, extensive engine idling, first and subsequent use of AMSOIL in vehicles with over 100,000 miles, daily short trip driving less than 10 miles (16km), frequent towing, plowing, hauling or dusty condition driving.
AMSOIL Ea full-flow oil filters are designed for extended drain intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea full-flow oil filters."
If I can use this stuff and only change my oil once a year without concern, then I gotta say I'm in.
I'll search for other threads about this. Thanks for the tips!!
You are correct in the recommended OCI. For extended drain intervals, synthetic makes sense. I have never used synthetic in my 02 Maxima and probably never will. I doubt if synthetic will find a leak that conventional oil would not leak from. Most oil leaks are caused by worn seals and gaskets that dry out and crack.No need for synthetic if you are following the recommended oil change intervals. Over time, synthetic will find leaks, thats why it is even worse to switch to in an older vehicle or one with higher milage. Amsoil has great stuff, and I highly recommend their feul additive every 4k miles. But as far as oil goes, conventional 5w30 any major brandm My 2 cents hehe.
How would synthetic oil find a leak that reg oil wouldn't? If they are the same weight oil how is it possible? I'm not the the smartest guy and my posts may reveal that from time to time. I would just like someone to explain how this is possible, because I don't understand.
Dude, it's only like $20/year to become a preferred customer!!I'm thinking of becoming a dealer being I have alot of friends who would like to run it and a busy drag strip 5 miles from my home.
