    3000 miles? Conventional oil unless a very dirty area or you pull a lot, can go 5000 miles.

    I've never gone by the computer. I take a sharpie and write the mileage that I want to change the oil at on the drivers upper corner of the windshield and just keep an eye on it. I do all my own oil changes.

    It wasn't downgraded! They changed it to a high grade Dino with many synthetic stabilizers in it. Even the 15,000 mile extended is Dino. Redline and amsoil are true synthetics.

    I am going to try RP on my next change, getting that tick in it and hope this will help. I know I have a hard time getting away from the change every 3000 miles, dad drove that into my head when i was young. I know a few technicians up here that swear to change it every 3-5k miles just because of the huge temp swings we have in ND.

    On that list there is no true synthetic, I use Redline a true Group 5 oil, which means a true synthetic base. Most of the oils on that list use ground oil and they remove impurities and call it synthetic. They are very good quality compared to other oils, but they are not synthetic. Amsoil is close a guess the current knowledge is they are a group 4 oil. Mobil One had gone switched groups since it's inception, I believe it was group 3 and group 4 from time to time. Generally speaking I think it is the best OTC synthetic brand, and I have used it for years in various vehicles, but my Hemi only drinks redline, a true synthetic based synthetic oil.

    The indicator is amazing trust it. GM has had these a long time and they are very good. In the older 4th gens the light just goes on after about 3000 miles and it is not using algorithm like the new ones do to calculate oil life. 3000 mile oil changes even with conventional is a waste of money 99% of the time. I run Amsoil if I can but can't always get it in timely manner. It is available at Fleet Farm where I live but I want 0W-20 which they don't stock.

    Anyone want to educate yourself on grouping of synthetic oils read here. Different oils are categorized in-groups by the type of base stock they are made from.

    The hard part is finding information on where your oil falls. Nobody in the industry wants to be specific. However, on Bobstheoilguy many guys run oil analysis and have found some information on grouping. Anyone who wants to protect their truck and interested in extended oil change intervals, should be using synthetic whether it is group 3,4 or 5 (Redline)



    When choosing the "best" synthetic, it is a choice between group 4 or PAO's or group 5 Esters. Here is all you need to know about the two.

    Esters for Lubrication


    The bottom line is these are the best, but is it necessary to go over board with lubrication for a gas engine? That is every persons personal choice, I say if you change your oil every 3k miles you should just buy the cheap stuff. If you go 10k plus on oil changes you have to be crazy not to use either group 4 Amsoil & Royal Purple or group 5 Redline.

    Spread the word.

    Here is the reason I stop using Mobil One, they simply will not answer the question if they are group 3 or group 4. From Mobil One website. I have no doubt that Mobil One is high quality, but I doubt it is group 4 anymore, if it was they would proudly say so, lol!!! I wouldn't hold it against them, they all do it except the very specialized oil companies like Amsoil, Redline, and a couple others.

    I've heard quite a few people report that Valvoline Synthetic made their Hemi tick disappear... I'm going to give it a shot and see for myself.

    Just waiting to Hit the 20K Kilometers (12 K Miles) and then the Jeep will be broke in enough to start using Synthetic.

    In my Magnum I currently have Castrol and it seems to tick more than when I had Mobil one in there. Still up in the Air wether to switch to Royal Purple or Lucas. I change the Oil once a year and only drive about 6 K Miles.
