Im using amsoil full synthetic how often are you guys changing your oil using full synthetic, im running a 5th gen greddy turbo'd.

 

Most synthetics can easily go to 10k without any problems. However, since you have a turbo I'd stick to the factory spec of 7,500mi.

 

i run full synthetic mobil 1, but i still change every 3k. i want to keep my motor healthy.

 

usually 4-5k, my millege get quickly i drive only to work and home 80miles a day and sometimes i drive to store and stuff so daily put 100 miles

 

i usually do like 5k or 3 months and i run royal purple.

 

What'r you guys all smoking? Do any of you realize that Honda's interval is 7,500 miles, and that's with non-synthetic oil.. Synthetic oil isn't cheap either.

 

My Castrol Syntec Blend is black as night by 3000...

 

So? That has no bearing on oil quality. Run an oil analysis and come back.

 

I also don't feel comfortable with the consistency after 3k.

 

Yeah, I noticed in the manual the recommendation of every 7500 miles under "normal conditions," which means very little stop and go driving and few short trips. 3-5k is probably fine for most people.
I'm sure it's far more important to keep the level correct than to keep new oil in it.

 

i drive 90 miles a day so i change it every 3k..

 

The reasoning in this thread is starting to hit rock bottom.

^agreed

If youre really interested in how long your oil can last between changes, get your oil analyzed by Blackstone. I use Mobil 1 Synthetic and a K&N oil filter, and my oil was still fine at my last oil change interval of 8,000 mi. Ill probably go for around 10,000 mi until my next oil change.

 

I probably do almost a full oil change every 3000 miles adding oil to replace the qt I burn every 1000miles on my 97 SH

changing your oil at 3k is doing nothing better for your engine than changing it at 5k, as long as you aren't using crap filters.

Spending $40 an oil change isn't cheap people.

Do you even know what that means? Ugh people are their stupid assumptions.

Check your oil after 1000 miles, it will just as "black" as after 5000 miles.

 

about every 5-7000 miles, depending on how lazy i get...


p.s. i'm constantly adding oil maybe 1 qt a month, so between oil changes, my car is getting new oil....

 

The All-Know-It-All Matt steps in, Listen guy .. Most people don't even think about driving 7000 miles before changing their oil. I change mine around every 3000 miles and so do most people on this forum. oil gets black near 1000 miles, but not as black as 3000 miles. Sure color doesn't mean much when it comes to oil, but its viscosity does. Driving on the same oil for 7000 miles, the oil would fell more like Black liquid water than like oil. I don't think that's necesarilly safe for the motor do you ?
BTW, I heard you can't sell your car, after something like 3000 views and about 3 months of it being online, Pathetic. Quit being an e-Nerd and an e-*** and actually help some people on this forum.

 

I run mobil 1 synthetic and change every 3k-4k miles

I just did and you decided to step and and spit some bullshit story about the color of oil and some other bs about viscosity. If you want to correct me, go read.

You call me a know-it-all yet you're calling honda engineers idiots for giving a 7500 mile service interval. The word hypocrite come to mind?

You can change your oil at 3k miles if it makes you feel better, but know, that you are wasting your money and time. Next time, take a sample, and send it to a lab for analysis.

Personal stabs at my car sale. Mature. It seems everyone on h-t wants it, based on some ***umed number of $$ they're getting for their totaled car, gets the insurance call and realizes they can't afford it. After 3 of those and a bunch of local people that didn't read my craigslist ad correctly, I gave up on trying to sell it.

The market for a black car with a black leather interior with no ac is small enough. Add to that no power steering, all the other stuff I've done, and you have a tiny market. I'm happy I didn't sell it now anyways. So thanks

 

From calsci.com

"Synthetic oils have a higher viscosity index than mineral base oils. Synthetics have better resistance to thinning at high temperatures and thickening at low temperatures. Since synthetics have little or no VIIs, synthetics last longer in service without radical changes in viscosity. "

whenever i remember and when I'm not lazy. I can go 6 months and only put 3k on the car so usually every 3-4 months

 

So far this thread has two people that actually know what they are talking about. mgags7 and vinuneuro. They have posted facts, and pointed us to the right source of information.

I myself run AmsOil with a by-pass oil filter system, and I generally change my oil about once a year, usually in the fall before the colder season. I have to add a quart fairly often (About 1500-2000 miles) based on my time in VTEC. If I drive it nice I can go about double that without adding a quart. I put on about 15-20k miles per year. I too have had my oil analyzed after about 10k, and the test has come back good after that many miles.

People who change their oil every 3k miles are suckers for the auto and oil industries having been in bed together for years.

I spend roughly $30 for synthetic oil + Mobil1 filter, every 3-4k miles cuz I'm a balla like that!
