oil change question
It has been about 6 months since I changed my oil last and I have put like 400 miles on my truck. Some people have told me to just change the oil like every 4-6 months and only change the filter like once a year since I only put like 1000 miles a year on it. What are your thoughts on this?

Re: oil change question
Changing your oil without changing the filter is like taking a shower to get cleaned up and putting on the same socks you were wearing when you get dressed. IMO change the filter and make sure you use a filter that has an anti-drain back feature. Your filter holds about a quart of fluid and that represents about 20% of your oil capacity so in a sense your are leaving 20% of the old oil in your engine when you just change the oil.

Re: oil change question
any decent oil will not lose any substantial amount of viscosity after only 6 months and 400 miles, so I wouldnt worry about any damage from not changing it, in a case like yours (and mine) its best to just play it by ear, pull the dipstick, feel the oil as compared to new oil. if it is noticably thinner or darker then i would change it

Re: oil change question
the problem is not so much the oil breaking down, but getting contaminated. Theby products of combustion is very acidic.
I would fire up the truck every weekend, let it get to oporating temps. This helps burn off contaminantes. Then check the oil's condition every week too. 4 to 6 months isn't all that bad if you are always checking the condition. As for the filter.... I'll agree with every one else... it is like taking a shaower and putting on underwear that you've had on for a week. Given the option of chainging oil only, or filter only... I'd chainge the filter alone. |

Re: oil change question
Agree, change the filter at every oil change and be sure that the filter is a quality one. It is your choice on the oil change with the low miles. The fact that there are very few miles on the oil means that there are low contaminants and acids in the oil, however, sitting in a shop or garage that is not heated means that a chance of some moisture buildup in the crankcase is possible. I am not planning on changing my oil as I come out of my storage this year, but I do have a garage that is temperture controlled.

Re: oil change question
Change the filter like everyone has said. Filters do their most good on the first pass anyway. Try to stay away from FRAM filters and go with a WIX,they trap up to 45% more dirt that fram on the first pass.JMO

Re: oil change question
AC delco seem to have the best anti-drain back valve. My 02' Surburban has a case of cold start rod knock that GM says is fine. As long as I use an AC Delco filter i don't usually hear it, but when I messed up and got my oil changed at wallyworld (They used a cheapo filter). I thought I threw a rod when it started up the next morning. Needless to say all I run now is AC Delco.

Re: oil change question
that's piston slap, not rod knock.
A NAPA gold filter (1060 for small block) is a rebadged WIX, at a fraction of the cost. I have cut up a fram and a NAPA gold, they are both sitting in my tool box at work.... night and day. I'll NEVER run a fram again...ever. |

Re: oil change question
It has the piston slap too but it only does that on really cold mornings. I have one of those engines that have a rod knock issue too. It only happens when I run a cheap filter though.

Re: oil change question
Lightweight filter media in fram,not very many pleats.WIX has ALOT more pleats and heavier filter media-BETTER CONSTRUCTION! IMO

Re: oil change question
There is alot of difference in the filters...and actually the Napa filter longhorn is talking about is a rebadged wix case...the wix filter is actually the exact same internally as the Napa Silver...the Napa Gold is a little heavier and has more pleats than the Wix...Fram doesn't have near the pleats (increased surface area when stretched out) than the Wix or Napa filters...and acutually my Napa dealer cut open an Amsoil filter (the regular oil filter...not the bypass filter) and the Napa and Wix beat it also in pleats and weight of media. I only put Napa Gold on my trucks...diesel and now my 70 C/10. I have heard of a man that changed his filter every 1000 miles and added a quart...never changed the oil completely...supposedly had over 300,000 on an early 80's 350 in a half ton..over course he was an older man and mainly commuted in it...but I thought that was an interesting idea.

Re: oil change question
I changed over to the NAPA "Gold" filters awhile back and with the oil filter specials that NAPA runs on a semi-annual basis, I can save some serious cash on filters for all of my vehicles. They are a good filter.
