FACT: AMSOIL synthetic motor oils exceed the most demanding world-wide performance specifications, meeting warranty requirements for all domestic and imported passenger car and truck engines. "I have seen an 8% increase in fuel economy in my Corvette engine powered Z28. With my driving I'm spending about $3,000 per year in fuel. An 8% savings comes out to about $240 per year. With my Amsoil oil and filter changes costing me about $55, that makes Amsoil FREE for me, plus I am profiting almost $200 from it. I really don't see how people say Amsoil is expensive. When you're being compensating by something else to offset the cost, how can this be expensive?" -Robert Riley In 20 years, engine speeds have increased 50 percent. Modern engines are smaller, leaner burning, hotter-running, have higher compression and use smaller radiators and oil sumps. Over the same period, oil drain intervals have increased as much as 300 percent. |

AMSOIL 0W-30 HIGH PERFORMANCE Fully Synthetic Motor Oil. Lasts up to 1 year or 35,000 miles, whichever comes first. I highly recommend this over any other 30 weight oils. I only use this oil in my own vehicles. This is AMSOIL's top-of-the-line oil. Use in place of 5W20, 5W30 or 10W30 oils. This is the stuff you want. 
AMSOIL 5W-30 Fully Synthetic motor oil. Lasts up to 1 year or 25,000 miles before needing to be drained. 
AMSOIL 10W-30 Fully synthetic motor oil. Drain every 25,000 miles or 1-year, whichever comes first. Works very well. I recommend the 0W-30 over this if it's within your budget. 
AMSOIL XL 5W-30 Fully Synthetic Motor Oil. Drain every 7,500 miles or 6-months, whichever comes first. This is Amsoil's lower cost synthetic, but has to be changed more often than the others. I recommend the TSOQT over this when possible. 
Amsoil Engine Flush - recommended if you have over 10,000 miles on the engine. (For use with gasoline-powered engines & small lawn equipment, except Diesel) 
Amsoil P.I. Quick Shot. I recommend pouring this 12 oz. bottle in the gas tank about every 4,000 miles to clean out the fuel injection or carburetor and lines. This works very well! For use with gasoline-powered engines & small lawn equipment, except Diesel)
