    Re: synthetic oil

    Ok guys, question...how about time? My car does not get more than 8k a year so if I can increase up to 7-8 k of mileage for syn, can I extend syn to a year or so? Or even longer? Moving to an apt soon, so it would help to run longer....

    Re: synthetic oil

    It depends on the oil your using ,but I know Toyota says with their synthetic you can go 10,000 between changes instead of the recommended 5,000.

    Yours being a newer vehicle I would be surprised if you really needed to change yours at every 3,000.[/QUOTE]


    IIRC, about 15 years ago most manufacturers recommended 3k oil changes. It wasn`t to the idea of a LONG oil change became a marketing technique that manufacturers started extending the life of their recommended maintenance.

    I believe Motor Trend had an article about this, talking about about the "new" extended" intervals and how the car companies where extending the recommendations. When they looked at the year to year recommendations they found that most companies where still using the same exact motors as the previous year and they same oils. Nothing changed but the recommendation.

    Re: synthetic oil

    This topic is very interesting and so are the comments.

    I have a VW Jetta and according to the service manual and the shop they call for oil changes every 10,000 miles. And the first few oil changes were on the dealer so thats what we did. For me this is great as my wife drives a lot for work. I am now doing my own oil changes, and there is no way I would go down to 3 - 5,000 mile intervals.... The oil that the Manuela calls for is like $9-10 a quart!!!! It is just over $60 for me to do my own oil change with the correct oil. The dealership want $75+ for the same thing; and the quick lubes won`t guarantee that they are using the specific oil because they only have their standards. The other big thing is I don`t always have the time to do an oil change every other month or so.

    If you are changing your oil every 3-5,000 mile then I think Std or even Syn-Blend oil is the way to go to keep cost down. But if your are trying to go 10,000 like some of the new vehicle recommendations then Full-Syn is the way to go.

    But then again this is only my opinion.

    But this brings up the question... Is VW oil REALLY better than a major brand (Mobil1, Castrol, Pennzoil).... I mean it is doubtful that Audi Group owns their own oil refinery so what you are likely paying for is rebranded oil at a huge mark up...

    Sorry to be confusing...

    VW / Audi spec out a specific oil. My local Auto-zone has a Castrol Syntec 5W-40.
    Link: Castrol/1 qt. SAE 10W-40 Syntec full synthetic motor oil (6246) | Engine Oil | AutoZone.com

    It says it is blended and made for their specifications. I did some research and the Dealerships use the same type of oil. (Not sure of the brand)

    But I was more disturbed at the price per qt. At this point I will most likely be researching this as well before I buy my next car. I already look into insurance, Fuel type, Gas millage, Overall Quality ratting.

    Re: synthetic oil

    A lot has changed over the last 10 years. Engines burn a lot cleaner and oil technology with higher API standards are lot better plus engine oil capacities have increased as well. I recall when engines usually had a 4 to 5 qt max capacity (even V8`s) but now my V6 has 6 qt capacity.

    If someone really wants to know when to change the oil, one just needs to get used oil analysis. I believe it costs around $25 and the report will tell you the health of your engine and the oil. The data on BITOG tends to state that unless you are in temperature extremes or do high performance stuff changing the oil using the manufacturer`s recommendation will not reduce the life of your engine. You do not hear about any oil related issues with engines much which I think why some oil producers offer such life time motor guarantees. If your engine sludges, it is likely either to be not changing the oil ever or bad engine design (poor ventilation, improper drain holes, etc).

    The late 90`s early 2000`s Toyota 1MZ-FE 3 liter engines were notorious for this, we had a 2000 Avalon with that motor. We were on top of oil changes and it still sludged. Got to the point of poor performance and gas mileage; pretty much needed a rebuild at 64,000 miles. Sent that thing to auction

    Re: synthetic oil

    i say with high mileage car stick with what you were using before ...now i have been using conventional oil but will not switch to syn due to the oil viscocity that will sweep into small cracks and prone to damage..

    CA.detailchick. Check out Amsoil and my 2001 Acura gets a change ever 12,000miles or once a year.
    I use Amsoil in my Audi and Mercedes and I wont use anything else anymore. I used to use Mobil 1 Euro but I heard and read they changed their forumla. I change my oil about 10k-12k miles and its still pretty clean. I do use the Bosch High Cap oil filters.

    For your information there are oil changes on Bobistheoilguy going as long as 20,000 miles! Is oil added during the interval? Yes,obviously. Has the filter been changed multiple times? For the most part, yes. A used oil analysis has shown no harm to these non commercial engines. Extended oil changes to the extreme are possible providing you know what you are doing and keep tabs on the oil along the way.

    Re: synthetic oil

    My neighbor has an Audi A4, I think its the same 2.0 turbo that VW uses, He buys Mobil 1 0-40W at the local Walmart, I help him change the oil sometimes, they (Germans) sure like to make things overly complicated. He goes 5k miles between changes.
    In my Ford, I like Pennzoil Ultra, its about two bucks more per 5 quart jug at Walmart, and I firmly believe in changing every 5k miles too, course mine is sure easier to do.
