Glad I'm running Mobil-1 Synthetic!
 

Well my truck sat outside all night in 6 degree temps with a wind chill of -2 degrees! This morning my truck was so cold the doors stuck a bit even though I havent washed her since last Sunday! I turn the key to start it up & Vroom she started right up! There was a minnor grind from the starter motor gear slowly backing away from the flywheel, that happends on every vehicle in sub zero weather, however the motor itself was extreemely silent & noise free as it reved up to 1200RPM+, immediately in this type of weather! I'm glad knowing that my 5.4 3v is being protected by a synthetic! No dino oil will protect as well in these conditions! Suppost to be even colder tonight!....:smoke:

:smoke: indeed, but what are you smoking?

... wind chill doesn't affect inanimate objects in the long run - your truck only got down to 6 degrees. In the short term, sure... it will cool down a warm engine faster.

I'm running a synthetic blend and haven't had any issues. And the actual temperature here was -1 °F this morning. But my truck was in the garage so it wasn't that cold. We'll see how it does after I get out of work today.

Now I just need to install a remote starter... the engine does fine in this weather, but I get pretty damn cold waiting for the truck to warm up :eek:

I start my truck up in -40 with dino oil, always fires right up, no problems, no grinding sounds.

That's fine for you & your truck, however I noticed immediately from my 1st oil change, at 3Kmi, my 5.4 3v did not make any ticking noises on a cold start, after dumping the factory fill 5w20 Motorcraft Oil for 5w20 Mobil-1 Synthetic. The ears don't lie, ticking means metal/metal contact until a thin layer of oil gets in between those parts.........Synthetic is a much better protecting oil for any climate......hands down.......try some at your next change, you will notice a difference.........:smoke:

I'll pass thanks, the extra expense isn't worth it. FYI I had a jetta with over 200,000 miles on it, all it ever had was dino oil, not even the blended stuff. Never had engine troubles with it. When I sold it the people wanted a compression test done on it and it checked out just fine.

It's been -1 here the past couple of morings and no odd noises from the engine using M-craft blend. The m-craft is a very good oil, take a look on the bobistheoilguy.com. Also not to knock M1 too much, cause it is a decent oil but last info that I had it is not a full synthetic anymore, there is a loop hole that lets them still advertise as being a full synthetic. For the money of M1 you can get better oil at close to the same price.

Stealth where do you get all these forum pics :confused:

:lol:

Also you're probably not getting noise on start up now cause M1 tends to run very thin. For example the 5w30 is actually closer to 5w20 instead. I'm not sure how much thinner their 5w20 is but I know the 5w30 is too thin to run in GM LSX based engines which call for 5w30.

When I find them I add them to my gallery for future use, situations such as these. :D

He's right, I use 5w30 Mobil 1 at every oil change w K&N oil Filter.

Keep em coming buddy :thumbsup:

Funny, there are plenty of guys on here that sing the praises of synth lubricants, and those that say they are more hype than anything else... While I am no rocket scientist, I do know the experiences I have had with regular well oil, and synthetics.

My 1984 Jeep CJ-7 was run exclusively on well oil from the time I got it with a fresh rebuilt 4.2L, until the day I got rid of it. The drivetrain was solid as a rock, I could not however say the same for the sheet metal which had decided to rust out on me.

My 2000 Ranger turned 100K trouble free miles on me running the Castrol Synthetic Blend from the first oil change when it was new until trade in day.

My 2004 F150 ran Castrol Synthetic Blend until it hit 50K miles, when I switched to Royal Purple. Mind you, the same day I did the oil change, I serviced my K&N as well, and I had set my tire pressure BACK to 42 PSI after the tire shop set them at 35 (I am gonna slap that twit the next time he does that!)... I noticed a 2.5mpg increase in City MPG, and 2.1 mpg highway. I find the engine idles smoother (the tach needle no longer twitches at the stop light), and the ticking at idle is gone...

Make up your own mind about the lubricants you use. My truck is a LONG term investment for me, unlike so many here that are trading off their trucks in 2 or 3 years, I will likely keep mine for 10 or more years depending on how my vehicle needs change. I fully intend on keeping my truck in as good shape as I possibly can during that entire time.

I've tried a few different oils in the TA in hopes of something that would quiet the engine down some and had no luck. But I always run synthetic in it for 2 reasons. I don't put many miles on it and feel more comfortable with changing the oil once a year if I'm running synthetic. The second reason is some times I like to run the hell out of it and with the engine turning 6k RPM's synthetic make me better. I don't know if actually helps or not but I run a full synthetic in the car such as Amsoil but I might switch back this spring to "German" Castrol cause it costs less but can be hard to find.

As far as the truck goes it just takes too much oil thus too much cost to run full synthetic. Heck the oil analysis on the truck comes back looking good with 3-4k mile oil change intervals. The wifes Honda oil analysis came back saying it look great at 5k miles and could go longer. These are with the M-craft blend.

Btw I think I posted here berfore about the extend OCI for my truck that Blackstone labs said I should not go longer than 4k miles on the oil because the additives are used up. This makes wonder why Ford says they should go 5k? I know every engine can differ some and the driver can play a factor in this as well. I drive the truck with a very light right foot( very rarely does the RPM's go above 3k) and about 70% city and 30% hwy. Just some info if anyone wants to run longer between changes using M-craft.

MC Synthetic Blend should be fine for most of us, unless you live in an area where the temp drops below 33°F or you prefer to run synthetic oil.
