My 2007 Mark LT has a flat spot or delay when I start the truck right at the first turn of the key. It starts fine but is this a sign of trouble?

V-6 motor. Battery dead. Anything I should do before I jump start it? Car is in Southern Cal so weather hasn't been a factor.

Had my first smog test for my 07 Mark LT yesterday, 68000 miles. It passed with zero emissions. I was amazed. I have run maintenance dose of Redline S1 since about 15k miles. Also, about once a year, a dose of MMO in the gas.

Both of these are 50/50 mix coolants. Any issue if they are mixed into a system. Drain and fill with one or the other?

Since new, I used MC semi Syn 5-20w for first 40k miles with 5k OCI. Truck never burned oil. Switched to PU 5-20w and truck started to burn oil. It burns about 1qt. every 3500 miles. I am now on my third OCI with PU and it still is burning oil. It’s not a big deal, but I’d like to hear you...

My truck burns about a quart of oil in 4k miles. Should I ad a full quart then or should I be adding a half quart when it down a half quart or does it matter. Oil is PU.

What do you like to use to clean/polish chrome?

I have the 5 qt jug in SN and 1 qt in SM. Total of 7 qts going in. Any reason not to so this with PU. I can't find SN quarts. SM is still on the shelf's at Walmart

2007 doesn't go off road except some dirt roads. Stock wheels. Was thinking Bilstein but cannot figure out between the HDs and the 5100's. Any other suggestions.

Is it really necessary to go to a high mileage oil if you have done 7-10k OCI with a synthetic oil on any car or truck after lets say 100k mileage? Can you stick with what I've been doing?

I had my dealer drain and fill my radiator at 50k miles. First time it was changed since new. It's suppose to go to 100k but i know better. I have put 800 miles on it since and going over my engine today, I opened the antifreeze overflow bottle and to my amazement, the color of the antifreeze...

In a new car, if you run a maintenance dose of let’s say Redline S-1 EVERY fill up. Would you ever need to do a full bottle treatment again? In a used car, once you run a full treatment of something like Redline S-1 or Techron, then you run a maintenance dose of let’s say Redline S-1 EVERY fill...

This is my Mother In Laws car with 18k miles on it. Bought new. 5k OCI from the dealer, 5-20w. This car started to burn oil during the 10-15k miles. I checked the oil yesterday. It was down 2 1/2 quarts with 3K miles on the oil. Make up oil is 5-20w Motorcraft semi syn. Any ideas why this is...

What is the best way? Also, is it safe to clean the straps? My straps get hung up all the time trying to retract back.

Ford is putting a OEM Re-manufactured 4R100 in my Navigator. They couldn't get reverse to stop making a major clunking noise when shifting. My question is, is there anything I should make sure the dealer does before taking the truck back? Break-in, should I do anything special? Also, when should...

How much time do you let your car/truck sit before driving away after start-up. How about winter vs summer.

I decided to spend the time and clay and wax one of my cars yesterday. The car is white. I clayed the hood with a detailer spray and clay. It didn't seem to remove all of the contaminants after I was done so I decided to do it again. Still not completely smooth. So, I went ahead with a cleaner...

How will adding MMO change a UOA, if at all? If added at a OCI and if added the last 1000 miles?

When a 4x4 gets aligned, is it any different that a 4x2 of the same truck? In my case a Navigator or a F-150.
