I’ve changed my own oil and completed most of my own auto work for nearly 30 years. During that time, I’ve owned Jeeps, Buicks, Fords (lots of Fords), and number of other vehicles. I never gave much thought to the brand of oil I used in them, concerning myself only with the proper viscosity. To my mind, all oils were the same, and I usually went with the cheapest oil/filter I could find. Over time, I started using the manufacturer’s recommended brand as often as I could.
Last year, I came across an AMSOIL website while surfing the internet and decided to give their oil a try. I’d recently purchased a project car, an old FIAT, that was clinging to life. I wanted to give this car the best oil I could find, and AMSOIL was it. After running a couple flushes on the woefully neglected engine, I put in AMSOIL OE 5W30. The car runs great now and I’ve changed most of the other fluids using AMSOIL products. I’m sure any care I gave to this little FIAT would have helped, but the drastic improvement made in such a short time I attribute to these quality products from AMSOIL. I plan to run this oil exclusively as I turn this little Italian machine into a rally cross car!
I highly recommend this oil and all other fluids from AMSOIL.
I haven't officially changed over to Amsoil yet, but I have added a quart and a half. Already the Caddy has responded in a positive way. I was getting a 100 miles per 1% average on my change oil meter. Now, I receive around 121 miles per 1%. Also, at 65mph my tach said 2500 rpm; where as now it reads 2350rpm. Can't wait to change over; won't be long now! So far, fantastic product! Getting mileage and performance ....
The oil is not part of this review since the oil is the best. Trying to pour oil out of the gallon bottle is the only complaint. In short, it's a mess. There's no easy way to control the flow. I prep my new oil filters with new oil before installation. Trying to get a small amount of oil into the filter from the gallon bottle without making a mess down the side of the bottle is problematic.
I am the owner of a 2002 Silverado 2500 Duramax which I purchased new. It now has 319,000 miles behind it and does not show a sign of quitting. It has always been serviced with Amsoil since it was new, and does not to this day consume nor leak a single drop. I have maintained a schedule of oil change at 16,000 mile intervals and have no notion of selling or trading. GO AMSOIL
