Mobil 1, change every 10,000 miles, filter at 5000. I would go longer but thats two years worth for me. You may want to check if its safe to switch on a used car, but it may not matter , just remember hearing something about that.. But I don't know..

I use Conventional. Have never used Synthetic although I have nothing against it either!

I have a fleet of Toyota's at the moment. They recommend 5000 miles changes in city, 7500 in Hwy Miles.

Typically i change around 6000 miles.

On synthetic's The early versions had issues with seal deterioration but that is long since resolved.

I've seen where Synthetics are recommends for cold climates in the winter for the hard starts on the engine components. Then switch back to conventional for the summer.

each to your own, have fun.

The cost has to make CENTS to me though too..

It got to the point where the dealer I bought my Kia from does it almost cheaper than I can so I have it done at a little short of recommended by Kia so I should never have a problem with the warranty if needed. Tried Mobile 1 in a 350c/in. Chevy van with low mileage years ago & started burning oil real bad so I called their 800# & was told that it does happen in some vehicles & they wouldn't even refund the price I paid, anyhow with me you only get one time to make a first impression. Went back to Wolfs Head & no more burning or leaking.

sYN, Been on that kick for years. My '88 Toyota PU went 14yrs before I sold it and for all I know it;s still going. My '02 Tundra is @ 156K and sound as the day we brought her home (and for sale I might add) My wifes 2014 -IS250 and my -13 Tundra 5.7 liter are all SYN babies so, yes I'm Biased towards Syntheens.

I run synthetic - Mobil 1 - in my Prius, and in the other late model vehicles that I've owned. Based on oil samples I've sent out for analysis, I change the prius oil between 6-7k. I have also switched to Mobil 1 5w30 in all of my Briggs and Stratton powered equipment. Easier cold starts and less oil consumption.

Where I don't use synthetics -

My '71 Buick Skylark - the 455 still has the old rope style rear main seal, and it already leaks. It gets a steady diet of Wal-Mart "Super Tech" 20w50 in the summer and 10w40 in the winter.

My motorcycles/atv - I've heard enough stories about degraded wet clutch performamce on synthetics to bother. I run Castrol GTX 10w40 conventional in all of them.

hmmmm, only one option to choose from, but i use both.....

I use dino oil in the '03 silverado 205k miles and still going strong. Changed about every 5k - 6k miles.

I use synth in the '09 Acadia 90k miles, still runs good, changed about every 5k miles. the reason i use it in this car is because they claim the well known stretched timing chain issue they have in the lambda platform cars is related to the oil life.

interesting (to me anyway), this weekend i found that the 'low cost' 2014 chevy cruze requires synthetic.

Ive been usein Royal Purple for about 3 or 4 years now in my 03 f150. My wife gripes about cost so I said Screw it, tossed in some quaker state conventional oil and whamo back down to 12 mpg. Never again. I have since traded the truck for a smaller economical vehicle and havent changed the oil yet but more than likely R.P is goin in.

Many new cars and trucks come from the OEM with synthetic oil, well its not really synthetic but thats another story. Anyway the oil changes range from 7500 to 15000 miles, most are at 10,000 miles, this is not the same oil as the old days..

And if you run your oil 10,000 like I do , don't run the filter that long, like I said at 5k I change the filter and add a quart..

LOL, if I ran synthetic in the generator it wouldn't make 1000 rpm, it smokes big time when I shut it down, I think the rings are shot, need a new diesel.. I can dream no ?

Edit to add, Smitty help...lol :lol:

I say use which ever you like just use a quality brand. I use 5W40 synthetic in my diesel pickup because I use it mainly to tow a heavy trailer so I want the maximum shear stability I can get but used conventional in my V1500 Jimmy that I did mainly highway driving. The Jimmy had over 350K on the clock when I sold it and still didn't use a quart between 5K oil changes. Used Pennzoil 10W40 it's entire life and when I changed the timing chain at 200K the inside of the engine was very clean with no varnish or gum build up to speak of
