How many miles does everyone change there oil with full synthetic? I am using Mobil 1 right now and Jiffy Lube told me every 5,000 miles. Well this evening I was having some fun reving the car a and I am about a couple of hundred miles before I hit the 5,000 mile mark when I see a little smoke from the hood, is this normal if the oil level is low? So, I put 1 quart and went for another run for more fun and everything seems to be ok now, no smoking.

 

I suggest you check out your Owner's Manual, and see what Nissan has to say.
(it says every 7500, for any oil.)

BTW "...smoke from the hood" is NEVER normal.

+1. Recommendations are in your owners manual. Chock full of valuable information.

 

My manual says every 3750 miles

 

thanks for the responses.

 

every 3750 miles in my manual--->06 zr

 

OK here the straight skinny. Regular and synthetic motors oil trap and hold dirt. Neither is better. Both get dirty. I recommend that you stick with the recommendations in the owners manual rather then push synthetic for more miles.

 

I run amsoil 10w-30, and I go 7500 miles on a change...

Do what ever you feel comfortable with, but changing a true synthetic after 3k miles is a waste of money

Amsoil's website claims that under normal operating condition its' oil has a 25k mile life.

 

I change mine regardless of what oil I"m running every 3-3500.

 

I use RP and I change it around 3500 to 4000. When I used Mobil 1, I noticed the oil was alot darker and thicker around that time. Which is why I switched.

 

There was smoke? That doesn't sound good. I'd check your compression and do a leak down test. I don't understand why it would smoke though? Was the oil low and did you check it?

 

Look again.

There are 3 different maintenance schedules, Premium, Schecule 1, and Schedule 2.

Unless you operate your vehicle

repeated short trips
Stop and go
dusty conditions, on rough, muddy, or salt-spread road
towing a trailer or camper...

then Schecule 2 (every 7500) is just fine.

"Schedule 2 features 7500-mile service intervals;..."


But your Nissan dealer would be delighted to have yu bring it in every 3750 and give them $150-250 to go down their checklist.

Actually, motor oil that turns dark is a good thing. It means there is more cleaning going on. (crap is being suspended in the oil).

 

When changing oil you have to look to countries that aren't all about marketing. BWW, AUDI, Porsche, and countless others are 10K+ on oil changes. BUT they don't use the crap oil we us. Class 3&4 oils (synthetic) can run much longer.

I do 7,500 with it on my TK. Nobody will ever know if that's good or bad. BUt if a E55 can go 15K, I think I can go half that.

 

The smoke you see may be spilled oil burning off on your block. Jiffy Lube is notorious for just dumping it in rather haphazardly.

 

I go every 5,000 miles on Castrol Syntec.

What was the level on the dipstick before you added a quart of oil ? A quart is pretty much the difference between the high and low mark on the dipstick.

You didn't jump dump a quart of oil in there right ?

 

everything depends on the style of driving. The more aggressive the driving habits the more often the oil & filter needs to be changed. The less aggressive the longer you can go without changing it.
I work at Walmart in the Tire Lube Express... and i see a **** load of different oil and filters, And i personally recommend Mobil 1 oil and filters.. you can never go wrong. I go from approx. 4000 miles to 4250 depending on if i get stopped at a stop light next to a rice burning civic with exhaust thinking he's the baddest mexican out there. ......NO OFFENSE {just seems like they're always mexicans.}
