Oil Change Intervals

[1st Synthetics]

Do you have a set Oil Change Interval?

If So How Often Do You Change Your Oil?

How Many Times a Year Does That Equal?

And That Costs What Each year?

Amsoil Touts 25,000 mile or One Year Intervals.

If You Changed Your Oil Three Times A Year Now, How Much Would You Save With One Amsoil Change A Year?

i usually buy all my oil when i catch it on sale. i bought 19 quarts of penns oil platinum at $5 a quart, so i am good for a while. i change every 8000 miles. the time duration varies due to me not knowing when i will be driving or riding into work. i am however, thinking about seeing if my uncle will buy all my penns oil so i can switch to amsoil!

[Thundare]

well for me Protection is everything, i change it myself, about ever 3-4000 miles with synthetic oil

5W-30 something.

There is no need to ever change your oil every 3K to 5K miles. AMSOIL is the only 100% synthetic oil on the market, and that is why we are the only oil that can go 25,000 miles or 1 year on a oil change.

I did a synthetic test a year ago in my commuter car and I checked it every so-often, started at 3,000 - oil looked fine. Then looked again around 5,000 - oil still looked good. Then again at 7,500 miles, oil started to look darker a little bit. By the time I got to 10,000 miles not only was it much darker, I had either burned some up or developed a leak (which I don't see because there are not any slicks on my driveway at all) ... the dipstick read way below minimum, so it was probably down a full quart and 1/2 maybe?

Since then, I said WHA?? and have been getting conventional oil and changing out around 5K and have not seen much loss during the last change or two.

What synthetic blend were you running Steve?

No Synthetic blend is designed for 10K miles that I know of.

I forget the specifics of what it was and was not supposed to do, how many miles, etc. I think it was Mobile 1, and perhaps it was something in my engine for all I know. I didn't think that it was worth the extra expense and trouble for what was essentially a commuter vehicle that I only drove 4 days per week to work and back home when it didn't seem to perform much better than what I was currently doing.

My goals now are to keep the vehicle running for at least 125k (it's at 90k now), get the interior/exterior cleaned up a bit and just keep rolling so I don't have another car payment for the next 2 years give/take.

[1st Synthetics]

Ya Mobil 1 is only good for 5k to 7.5K depending on witch line it was. Good oil just can not do the extended drain interval with it.

I run Royal Purple full synthetic 10w 30. With a KN oil filter.
I chanded filter and added a quart @ 4,000 miles then at 8k I will do the same, then @ 12k completly change everything.
Its about 46.00 w a filter for all 6 quarts when I started on sythetic.

Royal Purple is one of only a handful of marketers using Molybdenum Disulfide (Moly) in their oil formulations. Molys have the the potential to come out of suspension in high heat and actually form into a graphite like substance causing engine damage.This is one reason Royal Purple does so bad in all tests. It also is not 100% synthetic, it contains conventional oil.

What do you recommend for a 99 5.3L with 116k?

I also would recommend the 0W-30 or the 5W30. The 0w is going to be a little better in cold weather starting.

Signature Series 0W-30 100% Synthetic Motor Oil Product Code: SSO
http://www.amsoil.com/products/images/thumbs/sso.jpg The industry benchmark in lubrication technology. Designed for those who demand the absolute best in motor oil performance. The exclusive “extended drain” formulation delivers superior engine protection and maximum fuel economy and exceeds the requirements of modern, high performance and older engines.

I use quick oil drain valve which makes oil change much easier. This ball valve has a lever to drain the oil, so you don't have to remove the stock oil drain plug with a wrench. I think it is really good idea if you change the oil yourself a couple of times a year. I bought one from www.qwikvalve.com

[poncho08]

hard to say when i change my oil becouse i change it every 5000 km it might be every 3 mounths to once a mounth i do alote of driveing acrose canada so ya lol

You know with AMSOIL you would only need to change it every 40,000KM or 25,000 miles.

That is a good idea, the valve.

I am at 5000 miles on Mobile 1 Fully Synthetic and my change oil light is starting to come on. I think it is not due to the oil quality but based on miles (how the computer registers). From what I remember, resetting the computer simply is to pump the gas pedal three times before starting the engine (with the ignition on).

I was thinking of stretching to 7,000 miles on the oil change... should I reset the computer or change the oil?

I would not recommend running M1 past the 7K mile mark without sending it in for oil analysis.
If you do this it will be a tell tail sign on how long you can run your next oil change. M1 is not designed to go more than 7K miles to my knowledge this is why I recommend not doing so. Only go as long as the manufacture of the oil recommends.Iif you want extended drain interval up to and over 25K miles use AMSOIL.

[freddie]

How much does the amsoil for my 2500 diesel run a quart? I know that there is a 15k and 25k amsoil but how much does it go for? I think someone told me that it take 10qts to fill it back up. Are the oil filters expensive?

[Tdaz250]

I Change every 3K miles with Mobil1 Sythentic 10W-30. Im thinking of starting to go to 5K but I change every 3 just so i know everythings good in the engine :great:

[kgibson181]

Every 3 to five thousand miles oil and filter for me. My dad got me trained on that cycle, and since I'm 16 with a bad paying job he pays for the oil and filter as long as I change it.

[2COR517]

I shoot for 2500 miles. Valvoline MaxLife synthetic blend 5W-30. Just switched to WIX filters. I bought the truck with 75K, now has 135K. Bought Tahoe with 145K, now has 175K. Neither engine makes a peep, and both start burning oil after 3K.
