Going to change the transmission/filter and transfer case fluid in a 2002 F150 4x4 SuperCrew with 4R70W transmission. Don't have manual, but think it should be Mercon V? Can anyone verify if Mercon V is correct and how many quarts for the transmission and transfer case? Also going to change the...

My 2012 Toyota Tacoma, 4x4 with the I4 engine is approaching 1500 miles. I am thinking 1500 would be good for the first oil change. A few questions, 1) is there a special break-in oil in the engine from Toyota that should be not changed yet ? 2) what oil filter should I use ? 3) what oil...

Doing oil change this evening on my '07 Mustang and noticed the power steering fluid is at the add mark. Manual says to use Mercon fluid. Is Valvoline DexMerc going to be OK to use, or is there something else that I should be putting in there ? Thanks

I am considering using NuFinish on my 2005 Yukon XL, 2007 Mustang and 1988 Suburban. Before now I have not been too picky about wax and have used Turtle hardshell wax about twice a year on my cars with pretty good results, long lasting bead. Paint looked almost new on my 1999 Ranger that was...

What are your opinions on the most durable auto wax ??? I am looking for the toughest, longest lasting, most durable wax/protectant to protect my vehicles from the magnesium chloride here in Colorado. I think Turtle Wax HardShell is pretty tough, seems to be tougher and better bead than the...

Here in Colorado in response to the big snow storms, the roads and interstates have been saturated with Magnesium Chloride. Noticed a little bit of discoloration/corrosion on the chrome trim on the side of my Wife's '05 GMC Yukon. We will now wash every time we drive. Is there anything that...

Checked the transmission fluid in my Chevy Colorado with 1700 miles on it today. It is right at the add mark. So I want to add some fluid. Manual says Dexron VI, all I have is Valvoline Dexron III. What brand is best for the Dexron VI and where to get it ???

Is there any additive necessary when using Mobil 1 75w90 in a 2005 GMC Yukon with locking differential ?

Got an '06 Chevy Colorado with 3.5 I5 that sat on the dealer lot for close to a year. My inclination is to change it sometime before 1000 miles since the oil sat in the vehicle so long. Also I usually do a change on new vehicles at 500 or 1000 miles. Does GM use any special "break-in" oil ? Also...

I have used Valvoline durablend in my '99 Ranger with 3.0 with about 165,000 miles for the last 50,000 miles or so. Prior to that Valvoline dino. In my wife's 2005 Yukon ran Valvoline Dino till about 8000 miles and switched to durablend. It now has about 12,000 miles. I am considering switching...

I just got an old 1968 mercury with vinyl interior, some of the parts are a plastic with a chrome finish like on the gauge cluster and trim on the dash and door panels. What kind of cleaner/preservative will work on these parts without damaging the chrome finish on the plastic ? It is still in...

Hi Labman, what is an ecore ? Still not sure why this has anything to do with length of the filter. Both are pf1218 purchased at the same autozone, one recently and the other six months ago. Didnt check the inside of the filter. Old one is disposed of and the new one is now on the vehicle. Is...

I just got an AC Delco pf1218 for the oil change on my 1988 GMC Suburban. The new filter is about half an inch shorter than the one I removed and also I am sure that it was nearly twice the price as the same filter that I got for the oil change six months ago at the same chain store. I have...

At what mileage should the factory differential fluid be changed out of a new GMC Yukon ? What would be the best fluid to use ?

I changed the oil/filter in 2005 Yukon XL with 5.3. Refilled with 6 quarts as the manual says. Right after changing the oil I started it up let it run a minute or so and then shut it down. Waited a few minutes and checked the oil. Right at the full mark. Then let it sit overnite and checked it...

When changing the oil on a hot engine, is it possible for the new cold oil to crack the block when pumped through the still hot engine. I know this can be a problem with cold coolant in a hot engine, but what about cool oil in a hot engine ?

For years I have used ArmorAll on the outside rubber trim around the windows on my vehicles with good results. Never used the dielectric grease recommended by GM. Thinking of starting now on my wife's new Yukon. Is the dielectric grease really better than the Armor All ? How much does it cost...

Bought some Turtle Wax Platinum Series Ultra Gloss wax at walmart the other day to wax my wife's new Yukon XL. I am comparing the label to the Turtle Wax Super Hard shell car wax. The Super Hard Shell wax claims that it outshine, outlast and outperform any car wax - or money back. If this is...
