They now have the 5,000, 7,500, or the 15,000 mile synthetic blend oils. I was wondering if anyone used it yet on our cars?

Until I see definitive results

15K oil = penny wise....pound foolish.

yea im on the 15,000 stuff testing it out for the forum
ive got about 6k on it.

i used the regular stuff before at 10k intervals and had it tested and it was always in good shape ready to be driven more

Like other's I'm waiting for some UOA's on these oils and then I'll consider using them. FWIW, regular Mobil Synthetic can easily go on 7500+ mile OCI's, so part of me is thinking that this is just a marketing ploy.

its a marketing skeme to make more money, id say go to costco and get a box of mobil 1 fully syn 10w30 motor oil for $24

i use mobile 1 on both my car and my sisters car and change the oil about 3500-4000 miles. so you don't have to change the oil all the way up to 15000 miles? but when i change my sisters oil in the gs 300 the oil is really black, doesn't that mean it needs changing?

changing oil that often is a waste of $$$ if your using syn. color doesnt mean its bad. the best way to find out is to get a sample of it and send it to blacksone labs for testing. you can get a free sample test kit from them and then send it to them and have it tested. make sure you get the TBN test, that will let you know how much life is left. mine has always been fine when i test it at my 10k change interval

I never take any chances... so I always try and change mine every 3K. On rare occasions I've let it go to 5K, which I smack myself for.... but I'm usually very good about doing it between 2800-3200 miles. I think thats one of the most important things you can do to a car.

If you're using regular oil, that's a good practice.

Comet2404

Yep I sure am. On another note... I hear its not good if you keep switching between synthetic and regular. Is there any truth in that? I plan on staying with regular oil anyways, but I'm just curious.

fsttyms1

used to be true, but youcan switch. but the question is why would you? syn is so much better for the engine

ou sig

that is a big time waste of money, even with regular oils, 5000 miles isnt bad at all

what is blacksone, is there a site where i can go to or something? how often do you change your oil with reg mobil 1? is it possible to switch from syn to regular?

with regular Mobil 1 i was 8-10k intervals

and yes you can switch, all you have to do is put in the syn when you change the oil
