    5w-20 in a 06 Dodge Durango?

    The owners manual calls for 5w-30 but I think that using 5w-30 in the winter would be a great advantage for short trip driving. This engine is the 4.7 v-8. Funny how the larger hemi calls for 5w-20, probably for fuel efficiency. I really want to try the 5-20 because of the short trips we make...

    Iron wear patterns

    If you look at a large number of Uoa's the iron wear rates seems to be lower with mineral oil when compared to synthetic oil. Granted most mineral oil oci's are shorter than synthetic oci's but is there something in a good dino oil that offers at least as good or better valve train wear?

    The L-300 Saturn has now made it's seventh trip to the dealer since 2001, four on a rollback. The last three times have been to replace a mass air flow sensor. To make a very long story short- I was taking my wife to a mothers day brunch last sunday when our Saturn decided to shut down on a busy...

    Now we are in the dawn of the new sm oil's and they look like the will do just fine. So now no matter how good the new sm oil's are doing and how the sl oils did in the past even when providing better wear numbers our panel of experts keep saying that synthetic oil is so better no matter what...

    Oil Filter Inspections

    Can a person get a rough idea of how clean the inside of their engine is by inspecting the inside of the used oil filter? I just changed the oil in my 04 dodge dakota 3.7 V-6 and looking at the inside of supertech oil filter it was spotless. Nice and clean with not a sign of sludge or varnish. I...

    The affects of short trips on oil

    Which type of oil would do a better job in preventing corrosive wear in a engine? A hdeo or a pcmo synthetic or a mineral pcmo. This is in relation to short trips in cold and warm weather. Interesting that my last oil report at only 2000 miles showed 31ppm of iron in the months of may and june...

    Point Blank- Will using a HDEO 15w-40 Hurt a new engine

    Yes I know about the warranty issues, but do you think with the tighter tolerances in todays newer engines that this oil would cause increased operating temperatures which could lead to greater wear? My concern is the new SM motor oils not containing enough zinc and phos. among other things. I...

    2004 Dakota Castrol 5w-30 Syntec Blend,2000 miles

    This oil was in use from December 29 until April 4 2004. I made three 200 mile round trips but other than that all were short trips. Distance to work is only about 4 miles one way so the oil does not really heat up. Most other trips were in the 20 mile range. I did not let the truck idle...

    How many of you are tired of all the mobil one UOA's

    M-1 is a firt rate oil and always will be. But holy horses such a large percentage of the uoa section is of this oil. Please post you conventional oil uoa's and other synthetics uoa's. I think conventional oil changed at reasonable intervals will provide the same protection and keep the engine...

I opened the box and opened one of the bottles and not to my suprise the oil was very fluid. Synthetics are very amazing in the cold. This is the ATM oil that is...

    New Dodge Dakota oil choice

    Two weeks ago I purchased a 2004 dakota club cab 4X4 3.7 v-6 with a five speed manual. I needed the extra room my wife had twin boys that are now one week old. The dealership was very straight forward in saying I needed to stick to 3 month or 3000 miles oil changes. They even made notes of my...

    More 15w -40 thoughts and questions

    There has been much talk recently about the benefit's of this grade of oil. I think the best value is in the high tbn's and the ability to run some what extended drain intervals while paying around six bucks a gallon at your local walmart. Also the ability to keep a engine very clean. But here...
