How Often Do You Change Your Oil?
 

I just switched to synthetic oil, but I'm having trouble finding out how much it lasts. I've heard it has to be changed every 5K miles, 10K miles, twice a year, or change the filter every 5K miles and the oil every 10K miles. I want to know for sure so that's why I'm asking here.:)

RE: How Often Do You Change Your Oil?
 

3 months for me. I rarely go 3000k miles in that time.

RE: How Often Do You Change Your Oil?
 

3000 miles or around 3 months, just like they recommend

RE: How Often Do You Change Your Oil?
 

I thought synthetic lasted longer. [&:]

RE: How Often Do You Change Your Oil?
 

i change oil and filter every 5k on the dot with mobil 1 synth 5w20

RE: How Often Do You Change Your Oil?
 

That's the exact oil I'm using.

RE: How Often Do You Change Your Oil?
 

i go just about 3k with mobil 1 5w-20

RE: How Often Do You Change Your Oil?
 

mobil 1 is the best out there to go 5k on

RE: How Often Do You Change Your Oil?
 

5000mi, penzoil platinum 5w30/w mobil 1 filter, actually notcied the car was running smoother with this brand as opposed to the mobil i used previously (but it all probably comes out of the sam factory)

RE: How Often Do You Change Your Oil?
 

every 3k miles and I use Castrol Syntech.

My GM Certified Tech Changes it every 3k or 3 mo. with Mobil 1 synth.

RE: How Often Do You Change Your Oil?
 

If you are running a good synthetic blend it is dumb/pointless to change it so often enless you drive the piss out of your car.... Someone said they chage it every 3k miles just like directed? Well its not directing you to do this... if i remember right it says like 15k miles or twice a year.... You guys are only wasting time/money.

I run mobil 1 and i changed it at 3k miles and felt so dumb for wasting my money.... the oil looked as clear as when i first poured it in.

RE: How Often Do You Change Your Oil?
 

Always have, always will!

RE: How Often Do You Change Your Oil?
 

See herein lies the problem!!! Yes... it says you can go 5k or more... heck... Royal Purple says it lasts up to 10k miles! But it says to replace the filter every 3k! What good is your oil at 5k... 10k... if your filter is bad? NONE! You are just hurting the motor! Now as far as Im concerned, if Im gonna get under the car to change the filter I might as well change the oil to! But then I run MotorCraft oil.... it's like $2.50 a quart! It's what the cars come with from the factory. Mobil 1, Royal Purple, etc. are overrated! Using a high tech motor oil is not needed unless you are pulling high HP numbers!

RE: How Often Do You Change Your Oil?
 

Ive ran Mobil 1 oil/filter since I bought the car, but this time im switching to Royal Purple just for grins. I change mine every 3K or every spring, whichever comes first. I figure with puttinghundreds of dollars into my engine for mods, why skimp out on oil to see how long it will last...

RE: How Often Do You Change Your Oil?
 

Clean oil = clean filter

RE: How Often Do You Change Your Oil?
 

I completely understand what you guys are saying.... But i think that you should change your oil according to your driving style.... I 95% of the time baby my gas pedal.. so less wear and tear on the engine so less need for often oil changes.. If i was someone who romped on it after every green light them im sure that i would change it more often.. but until my oil isnt so clear that it looks like brown water im not changing it so often.

RE: How Often Do You Change Your Oil?
 

Every 3K, contaminated oil = accelerated wear on the engine.

RE: How Often Do You Change Your Oil?
 

i chage mine 3 or 4 times a year

RE: How Often Do You Change Your Oil?
 

I have a 98gt and my manual states that you should change your oil every 3 months or 3000 miles.... THis may only apply to 96-98 models (may be different on 94-95 5.0's) . Also... My manual says to use 5w-30 oil... Not 20 like most of you use.. Like I said it may only be my hear of mustang...But regardless I use Mobile 1.. It seems pretty good.

RE: How Often Do You Change Your Oil?
 

Yeah it might be every 3K miles for conventional oil, but I've always heard synthetic lasts way longer. And I know my stang use 5W-20 bevause it's stamped on the oil cap.

RE: How Often Do You Change Your Oil?
 

Actually, "babying" and around town driving are the worst duty service you can have. If the engine never get HOT the water vapor and other low-end acidic nasties that are by-products of combustion never "burn" off--if you drive like that then you are in the severe duty cycle and should change the oil every 2500 to 3000 miles. It doesn't matter whether it's synthetic or dino, the bad crap will build up...[/align][/align]I drive a minimum of 100 miles per day, and 400 miles a day every couple weeks, at mostly highway speeds and change the oil every 3k miles (currently Pennzoil Platinum Synthetic 10W-30 'cause I can get itfor a very attractive price at a place near the Speedway in Daytona)--oil is a lot cheaper than engines...[/align]

RE: How Often Do You Change Your Oil?
 

Is 5W-20 safe to use in hot climate area "40*c"?
as i use FORD 10W-30 and change it every 3k.

RE: How Often Do You Change Your Oil?
 

I don't know if it's "safe" or not, but I couldn't bring myself to do it and am running 10W-30 here in Flroida... [/align][/align]If I was running dino I'd use 20W-50 (which is what we use in the older/other vehicles).[/align]

RE: How Often Do You Change Your Oil?
 

I start planning/thinking about my oil change at 3K. My Stang is my daily and I do a LOT of driving, so 3K comes up quick. I will absolutly not let it go past 5K, but I'd say an average oil change for me is after 4K. I don't totally believe that you need oil every 3K. I know overseas they'll go 10-15K miles before they do it.

RE: How Often Do You Change Your Oil?
 

Basically what everybody is saying is that no matter what kinda oil it is it gets dirty and nasty. As someone stated earlier it still looks clear, while it still may not hurt your car to keep it in there, i would rather have peace of mine and know that my oil is ok. plus our cars burn oil so after 3k it may be a lil low. between 3-5k is just a good habit to have.

And most companies base their claims on oil life on motors in general.Ppl that havestuff done to theirmotorspush them alot more than normal vehicles which may cause it to need to be changed more often. So like i said its just a good and safe idea. better safe than sorry

RE: How Often Do You Change Your Oil?
 

It also has a lot to do with the fact that very few people keep cars past 100k miles, you could run maple syrup and never change it and probably go 75k to 100k. I tend to keep 'em till at least 200k (I drove my '90 Miata to 245k, we had an '89 Celica with 322k).[/align][/align]My wife's RAV-4 has 165k and runs like a top having been on a steady diet of 20W-50 (Florida) changed every 3000 to 3500 miles--we're expecting another 10 years out of it (@10k/year)...[/align][/align]

RE: How Often Do You Change Your Oil?
 

Every 3 months.

RE: How Often Do You Change Your Oil?
 

2,000-3,000 miles and i change the filter and oil

RE: How Often Do You Change Your Oil?
 

if you are running syntheic every 5 K. This is in your service manual. Regular oil 3 K. I typically change mind between 4-5K with syntheic.

I use AMSOIL - Series 2000 Synthetic 0W-30 Motor Oil (TSO)

SERVICE LIFE
AMSOIL Series 2000 Synthetic 0W-30 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows: Normal Service(3) – Up to 35,000 miles or one year, whichever comes first.
I may decide this summer to change at around 7500 miles or so, but undecided as of now. This company I believe was one of the first to come out with full synthetic. Check out the following website if you're interested:http://lubedealer.com/crbsales/home.aspx
I also use AMSOIL ATF in my GT's manual tranny, filling about .75" below the fill hole - which has helped with the reported 1st - 2nd gear grind many are familiar with in the TR-3650.
Everyone has there own perspective on oil change interval and product. I'm putting my trust in a company that has tests and info to backup their products and has been in business forever. If my engine seizes up before my one-year oil change interval, I'll let you know. Good luck with whatever way you decide.
