    Had a 3 part Mobil 1 question:


    1) Using Mobil 1 & a FRAM oil filter, what would the correct oil change interval be?

    2) If I used a OEM filter could I extend the use life?

    3) The oil spec in my manual says to use 5-30wt, BUT, it's ok to use 10-30 wt for a one interval change, proceeded by a 5-30wt change next.
    After my 1st Mobil 1 5-30wt oil change, I am having a hard time finding 5-30 M-1 at the store. There seems to be an excess of M-1 10-30 though.
    Would I be able to use 10-30 in a AZ climate? ( I do go skiingg up north often)

    THX!!!!

    I check my oil regularly (synthetic Penn. Plat.) and wait till it looks used, or around 5k miles I change it. I have just been told by a mechanice in town that he changes his oil filter every other time he changes his oil. Not sure about that.

    Quite a few members here reccomend the OEM filters. Don't know about extending the intervals on changing.

    I have found the OEM filters are much better quality than Fram. Stay with 5w-30 oil. Its what is recomended, and since the VVT is actuated via oil pressure, Im not sure what ill affects 10w-30 would have on the system. The WalMart on Via De Ventura and the 101 seems to have plenty of Mobil 1 5w-30 in stock every time I have been there. If you get the 5 quart jug, and 1 single quart, it saves ya a bit of cash. I change my oil every 3000 to 4000 miles, but I dont think you should go any longer than the 5000 mile mark.

    fram filters are junk, we've cut them open and there isn't half the filter inside, also fram sells cheaper filters to walmart. I would not recommend changing the oil without a filter change. you could change the filter without an oil change tho. I'm going to change my filter at 2500mi, and the oil at 5000-7000, see how the oil looks.

    1. Change the oil every 5000. If you want to go longer, do an oil study. That's the only way to know for sure other than the manufacturer recommended schedule.

    2. No.

    3. Use 5W30. Pennzoil Platinum is also a good synthetic (I use it and OEM filter) that tested better on my Altima than Mobil1, though there's nothing wrong with M1 either. PP is also cheaper than M1, about $19 for 5qts at the local WalMart.

    I have mine done at a couple of different places. Caterpillar, Cummins South West, and there is a new place that my Fammily is going to try, but I have to send them the samples and cant remember the name.

    Chris just taste the oil to see if its still good. Oh and by the way use a Napa gold filter or hell use anything other than Fram.

    Found Mobile 1 cheaper at Advanced Auto parts than Wally world(Walmart). About $3 cheaper & no crowds.

    Question: I thought M1 Syn was guaranteed for 10,000 miles. And the extended version for 15,000 miles. I have a friend with a Mercedes & all his oil changes are free. The dealer uses M1 in his car & told him every 10,000 miles for oil changes.

    There should be some places near you that you can have your sample sent to. Many places provide you with the bottle, label, etc. at no charge.
    Do a local search for Oil Sampling Service, Cat SOS, etc. Its not very expensive, and its a good thing to do to monitor the health of your engine. :)

    Out here in AZ. Seems that Wally World is the most competative in price.
    The "High milage", and "Extended" oils are just hype. The High mileage oils have addatives that help to expand the seals in the engine preventing oil leaks. Problem with this is that when/if you use a conventional oil, the seals shrink back to the same size, or smaller, causing leaks to form.
    The "Extended" oils simply have more addatives. My samples have always come back really good useing the regular full synthetic Mobil 1, so I see no reason to change. When changed at 3000 miles, they are showing a 50% use, so if I miss a change or go too long, Im still good, though I dont see myself ever running an oil down to 5% or less. Personally, I feel good changeing when its near 50%.

    ^I agree, that is my philosophy as well. Besides, at every 5000 miles, it's only approx 2.5 changes per year.

    The only way to determine how often you need to change your oil is by getting an oil analysis completed, I use Blackstone Laboratories.

    That being said, I've run Mobil 1 5W30 (Tacoma) and Mobil 1 0W40 (Audi) close to 10,000 miles and the oil report showed I could have gone longer due to indicated wear metals and other metrics they measure. I change the filter with every oil change, but some dealerships and auto manufacturers suggest every other oil change. YMMV.

    Oh, one other thing. I only use their Fully Synthetic oil, not the High Mileage or Long Lasting, or whatever they are hyping now. For turbo applications, I've used the Turbo/Truck/Diesel oil and it seems to keep the temps down slightly over the Fully Synthetic version. The obvious indication if it's the Fully Synthetic is the Silver cap on the bottle (Red/Black/Orange is their other lines).

    Thanks for all the feedback.

    Wow! You guys are hardcore..oil testing.

    So am I to gather on the Mobil 1, once I start/started using it, I should not go back to conventional oil?

    You can go back. Only when running the "High Milage" oils is it not recomended to go back to a regular synthetic/dino oil.
    Personally, I think once you start running Mobil 1, you wont WANT to switch back to a dyno oil. :D
