Got a few questions.

I run 5w30 in my truck now, always have.

I've recently read up on '0w'

Being in a warmer climate, it seems to me, a thinner cold starting oil wouldn't effect me much.

But, I saw recently via the oil company that is selling the 0w oil, that it has increased fuel economy...

????

It's more expensive, like 5-10 dollars more.

Is it worth it to put in a 113,113 mile V6 engine?

What a bout a 4cylinder, Ford Focus, with 70k+ miles?

What oil filter type do you reccomend?

I use the FRAM tough guard on my truck being the higher mileage, and the engine runs a bit rough at times.


PS:
I'm having a horrible day, and can't think straight right now, sorry it's all jumbled.

 

No, if anything you should be going with a thicker oil in a warmer climate. As oil heats up it thins out. And as oil cools down, it thickens. 0w oil is lighter than 5w, so that would be for a Cold climate.

Stop listening to oil companies. Changing your oil regularily is going to give you better fuel economy.

 

See! A horrible day.

I use 10w-30 in my truck not 5w..

Ugh.

 

i use 0w30 mobile1.... no issues whatsoever

 

Not only what chainfire said, but running thinner oil in a higher mileage engine is asking for pre-mature wear and engine (usually lifter) noise. At 120,000 miles the tolerances in your engine are high enough a thinner oil isn't going to do it any good, especially once warmed up.

Just my $0.02. A good tune up and regular maintenance will do more for your fuel economy than running a thinner than recommended oil on a high(er) mileage engine.

 

Right on guys.

I was thinking the same thing.

I'll stick with the 10w30.

 

0W30 will not give you better economy. 0 is the weight when it's cold, W means winter, 30 when warm. If anything you'd use 5w20 to get better economy, but the gain is so little you'd never see it. Keep using 10w30 it will be fine, especially since you live in Florida and never see 30*. I've used 5w20 for 6 months trying to see if I'd gain anything and it was negligible.

 

Thanks Cole.

Although this winter, Jacksonville saw 17*F.

 

Just my $.02 but I would get something better than a Fram filter. I've had too many issues with the Fram's not having enough flow and starving an engine. And having a lack of a bypass valve. I've seen a Fram turn inside out and get sucked through an oil pump on a BB chev on an engine dyno.

I get Wix filters, aka Napa Gold. With a wix filter and castrol gtx oil i see no problem in changing oil at 7500 miles. Its still golden colored and has not broken down. And my truck has 127,000 miles.

 

X2.

0W30 is not going to help fuel economy, but it shouldn't hurt anything either. Personally, with your truck and location, I would just keep using 5W30.

Looks like I'll spend a few more $ and get a Mobil1 filter after reading this.

 

Napa Gold and Amsoil! I def. wouldn't go with 0w-anything. But thats just me!

 

i run 20w-40w castrol synthetic my truck

 

i use 10w30 even though the cap says 5w30... if anything just use straight 30 weight..... but yeah i would just keep using 5w30 or 10w30

 

I had round dee rounds with guys at work about this, I never heard of 5 W 20 before I bought my Ranger. I've been using 5 W 30 for ever in my Grand Marquis. Owners manual are the rules but there is an exception in mine about the occasional use of 5 W 30 when the weather is still above freezing. It make sense , the thinner it is the faster it will flow in cold weather. The Chicken or the Egg..... Now Synthetics ..worth the cash or not?

A buddy of mine sent me that link about 6 years ago, everyone who can "click" on that site and see just what is inside you favorite brand of oil filter.
You will be surprised.....

 

I'd have to say if your using your truck, like a truck, a synthetic probably has it's advantages.

 

NO, its a daily driver. I get to three months first before the three thousand miles. I tried Royal Purple in my Mustang but we only had it out for about 800 miles last year. I don't think I got my moneys worth on that oil change. I'll try a blend this year on my next oil change and try (if the weather lets us) to put a few more 000's on the odometer. Once the tops down...it stays down!!!

 

my cap says 5w30. since I have high miles, I run valvoline syn blend max life 5w30 and change it out every 5k miles. I've found that ford has back spec'd the 3.0 for at least as far back as my year to 5w20. same winter/cold weight, but thinner when warm.

SM oil rating has a decreased amount of Zinc which helps older engine wear. The Max Life line has a higher Zinc/ZDDP to put that back. I was at walmart yesterday and saw they have valvoline max life 5w20...I'll probably go to that once I run though my current stash.
