You have found the greatest source for the
best synthetic oil for your Kia Sorento

The same synthetic motor oil that 85% of NASCAR owners put in to protect their expensive engines when racing on the track.

If you want the absolute best oil, 2nd to none, then Amsoil synthetic is what all Sorento owners should be putting in their cars. Click the Testimonies link above and read about why so many race car drivers, police departments and trucking companies are using Amsoil and see the proof of why there is no better oil, despite all of the claims that other competing oil manufacturers make and often get sued over. 30 years and millions of miles of solid proof that Amsoil is #1 and FIRST IN SYNTHETICS. This is my actual 2003 Kia Sorento that I bought in December of 2002. I put nothing but Amsoil 0W30 oil in this beautiful machine. Haven't needed an oil change in over 10,000 miles and the oil still looks great! Oil and filter information for the 2003 Kia Sorento. That shows the mani stuff you can order right away.

After seeing the extensive tests using taxi cabs that was performed comparing conventional oil (what the majority of the world uses) vs. Amsoil, you COULD NOT PAY ME to put that conventional oil in any of my cars ever again.

I just put in the Amsoil synthetic ATF. With my own personal experience with this, it has worked miracles in other vehicles when I replaced my Dexron III with the same transmission fluid you see in the pictures. This only took a few minutes to change using the green vacuum. I just put the tube in and pumped the vacuum a few times and the oil was sucked out in a few minutes. NO MESS! To see where to get this tool, click go here and then click tools. I added about 4 quarts of the bunch that you see sitting on top of of my engine. I ordered extra to keep on hand. I use this same transmission fluid in all of the vehicles here.

When I put in the transmission fluid and motor oil, I wanted to be 100% synthetic all the way, so I decided it was also time to replace the cheap factory differential fluid with the good 75W90 racing fluid. I used the same suction device that I removed the motor oil with in order to remove most all of the fluid out of the rearend differential as you can see here on the right. The Sorento sports a 2.8:1 rearend gear. After driving the vehicle for a very short time, I noticed that the rearend gets very hot to the touch. BELIEVE ME, USE QUALITY SYNTHETIC OIL! Using all of the oils on this page will make your Sorento a MUCH more reliable vehicle. When I decided to remove the plug (which has a magnet built on the tip), I found it to be CAKED with sludge (almost like thick mud) and metal pieces. Look how much nasty stuff came off and my Sorento only having 13,500 miles on it when I wiped off this plug! Trust me - CHANGE THIS FLUID if you want your gears to last a long time. That's the reason they have removable bolts as this is a servicable part requiring maintenance. Lots of people never change the fluid and then wonder why they hear a loud whinning come from the back of their vehicle after they put a lot of miles. Use this Amsoil synthetic 75W90 gear lube and it will work wonders. NO additive necessary! Amsoil Series 2000 75W-90 gear lube highly recommended for your Sorento and lasts the life of the vehicle!
