You can switch to synthetic when ever you want but synthetic oil is usually made for vehicles with 100+ miles...

    its just about the same thing...
    but there are different brands...
    the best is Mobil 1 oil and Castrol oil...
    which are also expensive...
    Thanks for the rating!
    If there are any other questions you have,i will be more than happy to answer!

    with regards your comments about high mileage oils i suggest you check out Audi/Porche/Ferrari etc before you make your assumption as ALL these cars are FILLED with 5/30 FULLY SYNTHETIC oils from new and is recommended for the LIFE of the car.yes its MOBILE ONE OR CASTROL.(VW fill 10/40 gemini for cars with under 10k per year.and 5/30 for cars over 20k per year.)

    my answer is for American cars only...
    German cars which include BMW,Audi,VolksWagon, etc all use fully synthetic oil
    i personally have a 1997 BMW 5 series and i used normal motor oil on it and it has up to 210k miles...and now i started to use high mileage oil on it...
    it depends on the vehicle owner if he wants synthetic oil or not...
    but people prefer to use synthetic oil on German cars...

NO,its the other way around,you start with fully synthetic 5/30 upto about 75k,then go to semi synthetic 10/40(cost less) to about 150k,then go to normal 10/40 or 20/50 (cost even less).dependant on oil burn.

    Fully Synthetic Is Made For High Mileage...its better in quality and lasts longer...specially for vehicles with high mileage and burn oil...
    synthetic oil can be used any time...low mileage or high...
    but at a higher mileage it helps the engine to run smoother and stronger...

Using synthetic oil

I would switch to a 'Synthetic Blend' first - and stay with that for the next 3 or 4 oil changes (watching for any oil leaks to appear), before going to a full synthetic oil.

Hi ;) i have a 2005 subaru forrester 2.5 xs... Can you tell me what "fram" oil filter I should buy for replacement? and also I'm at 75000 miles now and the original oil I've been getting is 5-30...

No ... once you start the synthetic you should stay with it ... continue to use the recommended weight. 75000 is really no miles ... This engine should go for 175 to 200,000 properly cared for.

Your auto parts store that sells Fram can give you the proper filter.

I m looking to get my 75000 maintenance done on my Audi 2004 a6, I m at 76000 miles, the 75000 maintenance includes replacing water pump and timing belt... how long past 75000 is safe to keep driving, i am...

If the car has been kept up you shound not have any worries. I can say that you should be ok for another 5000 miles or your next oil change, Just remember it's PREVENTIVE manintence and it's important to keep the car in top shape. hope this helps.

OIl, synthetic or regular, what's the difference?

Synthetic oil won't break down as quickly as conventional oil, gives better protection and longer life. Excellent product, I Strongly suggested for those out there who forget to do their oil changes regularly or courier/ work vehicles.
Heres the link to an explaination from Castrol
I use conventional Oil in my jimmy with 5% of Lucas engine oil treatment and service the engine every 3,000 miles. I find it to costly for the Synthetic oil every 3,000 miles, and as for the high mileage oil you can buy. The high mileage oil has a higher fluid retention like adding Lucas engine oil treatment to any conventional oil, so you decide on what type of oil you like to use in your engine.
Good luck and hope this helps.
