I've decided to use synthetic oil in my Nissan 1986 300 ZX Turbo. I'll be having some other work done, but unless I'm actually standing there when they do the oil can I tell they've actually used the synthetic oil? There's quite a difference in price and I want to make sure I'm getting what I pay for.

Any suggestions> Confused

To be honest, there is no way to know if they do put it in unless you are watching as you said.If it is a reputable shop I would not think there would be a problem. Mobile one is a good choice or depending on what condition your nissan is in and mileage you could opt for royale purple, amsoil or redline.These are higher priced and you would have to do it yourself or buy them and have someone put them in for you. Sorry if this isn't to helpful.You might know this already, but the higher price for these is worth it for they will last much longer.The other synthetics that you buy besides these will last 5-6 thousand miles. The others that I mentioned will go 12,000 miles (royale purple)18,000 miles(redline) and 35,000 miles(amsoil-have to use their filters).I added all this for info only.

Drain a little oil out and put it in the freezer for an hour or so if it gets thick it's not synthetic!

I took my car for an oil change at a store that begins with a "W" and ends with a "Mart"  once and caught them trying to add generic store-brand oil to my car after I had dropped it off with Castrol Syntec off the shelf that I specified they use. One guy was carrying the Castrol to the other side of the garage while another guy, at my open hood, was opening the cheap stuff.  I leaned in and asked them what was going on and they were like, "Oh, is  that for your car?"  They kept shooting me the stink-eye after that but i got the GD oil I paid for.  Consequently, that was the last time I paid anybody to change my oil.  Rain, sleet, or snow.

You drive a Nissan and pay someone else to change the oil? And you read car craft?

i wouldn't spend a lot on high priced oil for an old nissan, no offense, unless the car has sentimental value. your best bet though is to change it yourself to make sure it is done right. "W-mart"'s lube center usually hires people that recently graduated there  Tongue special Ed Tongue . class if you know what i mean. plus i dont know 1 gearhead would accually let anyone else touch his engine.

You could send a sample of your oil to these guys for analysis.  The diesel guys use the heck out of this service.

The cheapest easiest way to tell if they put the oil they were supposed in the car is to hover over them and watch. Or, like my Dad always did. Demand the old parts and empties returned to him.

Like said befor..Car Craft?Payed oil change?! What the?How the? WHY?!! When I was 17 ,I got all dressed up for a hot date, Cool  had a 1/2 hr to kill, cleaned up my 79'Camaro a lil' more.Then noticed my 2000mile convenional oil change was over due.(I have higher standards with oil changes,now it's 5000miles with7500 synthetic.)Out came the ramps& cardboard in my dirt driveway only one drop spilt,on the back of my hand. DONE,in less than 15 min. I remember this because my freinds seen me,then later told my date."He loves his car,naw...CAMARO,more than he'll ever love you,..." If you think your cars a keeper, want it to out last 7 girlfreinds,(and counting) treat "her" right! And NEVER LET SOME OTHER GUY SERVICE YOUR GIRL!!!!!!! Wink

Good advice.  Drainning a bit of oil and freezing.  Inexpensive yet effective.  How about this:

I do my own changes and this is a good reason why.
