One thing I haven't seen in these most recent oil threads is "factual benefits" (not opinions) of using 10WXX and 15WXX oils.

 

Jesus! Just change your oil and drive the damn thing. Seriously. The way some of you obsess over the oil specs I wonder how you go about other purchase decisions. Like, does the cereal aisle in the grocery store send you running to the breakfast forum to debate the percentage of riboflavin? These aren't F1 cars folks. Try to remember that.

 

If one doesn't care for an oil thread......don't participate by contributing negatively.

 

 

I love it when Newbies throw their weight around.

You've been a member since 3/31/2013. Are you telling me you've never seen discussions like this before. Take your meds and regroup.

BTW: What "Car" are you driving? You didn't bother to fill out your profile data to list your car. Are you driving a Toyota or a Nash Rambler, or somesuch?

 

And for those who do care:

I use rotella t6 year round with a wix 51515 filter. I have no complaints. I change it every 6-8k miles, dependent on use.

 

Been running it in 3 diff vehicles for almost a yr now with no problems. I did check the oil in my uncle's 318 Durango(comparing it with our XJ and Blazer)recently and it was definitely different in color. Did a filter change and will change his oil in a few weeks. I also noticed it was alot cleaner inside the valvecover than it was when I switched his over.

Meanwhile here are some interesting tidbits pertaining to oil. Who says it's boring.

New Oil Change Regulations Start January 1, 2014 in Many States

The U.S. Commerce Department's National Institute of Standards and Technology has recommended the adoption of new standards for Motor Oil information on service invoices. So the next time you get your oil changed at a quick lube facility, repair shop or new car dealership, your repair bill should list the brand, viscosity and API service rating of the oil that was put in your engine. Shops are also required to have labels on all containers, including bulk storage tanks, that display the same information. Shops must also retain a copy of the repair invoice for one year after the date of sale.
The reason why repair facilities are being asked to do all of this is to hold them accountable for the quality of oil they are installing in their customer's vehicles. In other words, this new law is to help assure consumers that they are getting what they pay for, not a lesser quality oil, the wrong viscosity oil (which can cause problems in some vehicles) or the wrong brand or service grade of oil.
The new requirements go into effect January 1, 2014 in 20 states, with more states being added after the regulations are reviewed. The states where the law is in effect include AK, AR, CT, IL, ME, MO, NH, NV, NC, OK, RI, SC, TN, TX, UT, VA, VT, WA, WV and WI.

Watch Out for Poor Quality Oil in Quick Lube Shops

The quality of oil being sold by quick lube shops has come into question in recent years. The American Petroleum Institute (API) did a nationwide survey in 2013 to check the quality of oil being sold by quick lube facilities. Oil samples were taken from bulk dispensers in quick lube shops and analyzed in a laboratory to see if they meet API quality standards, OEM performance requirements and SAE viscosity grades.
The survey found that 1 out of 5 samples FAILED one or more of these tests!
The survey found that a lot of quick lube shops are selling poor quality oil that does not meet minimum service specifications or is not the correct viscosity grade. Poor quality oil increases the risk of lubrication-related engine damage and failure. For more information on this issue, see Motor Oil Matters.

 

Owned 2 out of the three, since you've shown a curiosity. Those with obsessive compulsive tendencies toward motor oil are the ones who should be on meds, old timer.

 

That's Mr. Old Timer to you.

 

Well, grasshopper, you still haven't listed what vehicle you own/drive. Is this a catch me, f**k me game?

 

Thank you! But you should really wait until you get time in before you respond like this. I do get what you're saying though.

 

.

I wouldn't be calling it obsessive compulsive, I would call it being a dedicated loyal jeep owner that wants the best of the best for there vehicle.No it isn't some 80,000 vehicle but to us our jeeps are like our baby's.And that's what this forum is for to ask questions and get good opinions and help from each other.So please go to another forum to say negative things.

 

gosh, I've never heard of most of these brands of oil! Here in NZ, we really only get the basics...castrol/mobil etc. My jeep (done 200,000km) needed a service when I bought it. As our temps here don't change a heck of alot, I did a bit of googling, and put Castrol Magnatec in it...and a new filter. I've always found it a good oil, although it was 10/40...but no drips/leaks, motor sounds nice n smooth....think I'll stick to that one. I reckon it's awesome that people are passionate about their vehicles to really study up before doing things....nothing wrong with obsession if it's going to keep your ride alive longer!

 

Us guys who hunt rant on about all the supposed advantages of the many different cartridges that are available when in fact the .30-06 will do it all. So why should us gearheads be any different about oil.

Forgot to add that I don't have a .30-06.
