Some say right away, some say 1200, others say 5000, some 10000+

What do you think, and why?

When did you switch and what were your reasons?

 

I dont think anybody knows the answer to that

 

when it's 100k miles

 

My Nissan dealer recommended switching at the first oil change interval. The only reason for this was because there was little point in doing so earlier as the oil in there was perfectly good. You'll probably hear lots of opinions on this.

I switched primarily because it does provide better engine protection, especially during extreme cold weather startup conditions.

 

The best time, is right after you do a search and post a picture of the car.

 

I don't need to prove myself to you, and I've done a search, and none of those significant threads with more than one page had any poll conducted. I thought it would be helpful to have one done.

 

Im still running dino oil at 7k miles.

 

I switched to synthetic oil at 3,750 miles.

 

i just switched it when i bought it at 15k miles. but i'd say first oil change if you're buying it new...

 

I switched to synthetic at 10,000 miles.

 

In the morning after breakfast.

 

I switched mine at 4,000 miles. Motul 8100 ftw.

 

changed mine at 4k, change it every 2k miles, even though people say not to really do it. Work at a dealership...so its cheap/free for mobile 1

 

Switching after 2+ years and 6K miles!

 

funny i just for the first time switch to syth. today after 8,200 miles and let me tell you its runs so much smoother that it is very noticable. as far as when to switch to it is basicly up to you. I used mobile 1

 

After I switched to synthetic my car ran like a cool Mountain stream cascading down the Rockies in the spring time--- Ah --- Oh , With birds singing the joys of life and the chipmunks and racoons frolicikng after a long winters nap.

 

i personally think it doesnt matter if your a stock car i switch like at 8k miles but i switched because i went TT. If your car is going to be stock then dont even worry for while after 50k plus miles then start thinking about it. Also it matters if you drive the car hard or not. Normal oil is perfectly fine people just used synthetic when you do performance upgrades and you need a more resistance oil. Because more heat builds up. Im no expert but look at those old *** sentras or crx's from the 80's some are still runnin without not engine rebuild and have over 150k on them with using regular oil.

 

The service manager at my dealership said 10k mi.

 

I will tell you the answer after you tell me how many licks it takes to get to the tootsie roll center of a tootsie pop.














I switched after my first oil change and have 0 oil consumption.

 

I switched at about 7k
