Review: Great Full Synthetic Motor Oil - I feel this is the very best full synthetic motor oil you can purchase and there’s a reason why. Don’t laugh I have a 2005 Chevrolet Tahoe that I used it on since day one with all my oil changes plus taking care of the Tahoe. My mechanic says everything with the motor is beyond perfect and he hears absolutely no strange noises or anything with it being 20 years old now. He is a firm believer in full synthetic oil then explained why it’s better. All oil will get dirty, but with full synthetic at last a very long time and does not work out or break down like conventional motor oil does one conventional motor oil breaks down that is when you have problems in full synthetic will not do that he told me. The only reason you’re really changing it is because of what he told me and it makes sense when your vehicle is running of course it needs air to ignite the fuel, and the oil is getting some moisture in it. They also told me it could be very dirty and it really doesn’t make a difference, but it’s the moisture that gets in from fuel burning, and the reason why it needs to be changed. Price I still can’t believe it’s very reasonable from all those years back and if you plan on keeping your vehicle for a long time, definitely use full synthetic in this is a very reasonably priced full synthetic motor oil.
Review: Eternal engine life - I have been using Mobil 1 since it came out in the 70’s. Excellent oil. Engine life is forever. I have 25 year old car with hundreds of thousands of miles.
