Great Oil

I have a 2018 Chevy Impala Premier & Chevy Colorado 4x4 4dr both with V-6 engines. I had the dealer drain the original oil and replace it with Mobil 1 5w-30 Oil. Previous vehicles had almost 325,000 miles each and I only used Mobil 1. I am a customer for life.

BEST Motor Oil I have EVER Used, bar none!

When I was much younger and running hot rods ('66 GTO and a '68 Mustang fastback Bullitt clone) I used GTX 20-50 and it worked ok in those cars at that time. As I have gotten older and, while my taste for fast cars hasn't changed, I now drive something a bit more refined, a V-12 Mercedes SL600 and a smaller V-6 Mercedes SLK320 Sport and I use strictly Mobil 1 5W-30 in both. Both cars run so smooth that at idle , and aside from the blurble of the exhaust system, you cannot tell they are even running. Mobil 1 5W-30 is the factory recommended oil for the SKL320 according to the sticker under the hood. The SL600 didn't have a recommended oil but I use the same 5W-30 in it as well. We also have a Ford Expedition with a 5.4 liter Triton V-8 and I figured that if Mobil 1 is recommended for a Mercedes, it's more than good enough for the Ford, too. I do all the maintenance on all our vehicles, except for any major repairs, and I change the oil and filter every 3,000 miles even though Mercedes recommends oil and filter changes every 10,000 miles. If you have ever owned a Mercedes and had to have major repairs performed at the dealership you know it can b e a rather spendy experience, so I would rather spend a little extra money on oil changes now than on major engine repairs in the future. Mobil, I absolutely love your product!

Should include a mileage reminder sticker

Excellent oil. I only buy the 5 qt size. I think you should include a windshield reminder label since you are marketing to people who change their own oil. Every 5 qt bottle should have a label attached.

Have used this product in my last 5 corvettes and can say that in my opinion it is a very good product and does exactly as advertised. I have never entertained the thought of another brand as this product has excelled in my opinion.
