Re: motor oil for hot climate

5W-20 is a far superior package than the older 5W-30's and 10W-40's and the like.<br /><br />Stick with the 5W-20. I have an '04' F-150 and use 5W-20 here in Arizona. I have seen my vehicle outside thermometer reading at 121 degrees. No problems here.

You will have "NO" problems with the 5W-20 oils, (as far as I have seen), They are all a semi-synthetic and will hold there vicosity fine in even the warmest temps.

Hey Walleyehead, Can I have your oil account? You could easily go to 4,000, maybe 5,000.

Not all 5W-20 oils are semi-synthetic. There are full synthetic 5W-20's and conventional 5W-20's.<br /><br />This is important because your engine must meet the Ford WSS-M2C153-H specification and carry the API license certification. Some of these oils will and some won't.<br /><br />Ford's WSS-M2C153-H specification is unique only to the 5W-20 viscosity. 5W-30 oils will not meet the spec. In addition to the basic ILSAC GF-3 requirements of other 5w-20 oils, the WSS-M2C153-H specifies a double-length ASTM Sequence IIIF test along with different allowable viscosity increases, limits of average piston wear, high-temp deposits, etc. The spec represents a long-life, fuel efficient oil.<br /><br />Ford's WSS-M2C153-H also uses the Sequence VI-B test for fuel efficiency. To pass testing, the 5W-20 oil must improve fuel economy one to two percent over a full synthetic PAO 5W-30 reference oil. Using a synthetic for a reference oil ups the ante, but some conventional oils pass. <br /> <br />It would be wise to use the WSS-M2C153-H 5W-20 oil Ford specifies, especially to maintain your warranty. It does not have to be Motorcraft brand.

I just saw this again, read my first post, and YOU got it wrong READING IT. Just the facts, man!

I think he was referring to your second post.<br />If you believe and wont change your mind, what is the point of posting? nothing anybody says will penetrate your fixed ideas.

Robby6950<br />Thats right!!! I was quoting your second post and didn't remember your first post info - sorryboutthat..... :rolleyes: <br /><br />JD<br /><br />
Originally posted by Robby6950:<br /> LD, I agree with the thinking that "Heavier is better" theory and its old school thoughts, but I fail to see what it can HURT? The reason I ask is in my 100,000 Astro Van, which called for 5w30, showed the oil pressure gauge fluttering at idle on a hot day A/C on, traffic, etc. Changed to 10w30 and no more flutter. Now its at 140,000 and its 10w30 summer and 10w40 winter and zero problems anymore. And many moons ago before going to Veit Nam, had a Ford 6cyl that burned so much oil I tried 80/90 gearlube! Worked, but would not turn over under 40 degrees, and anyone on a motorcycle behind me would pass out and crash from the sulpher fumes! It was fun being a stupid kid. So Boatneck, thats my take on your original question. Again, JMHO on another oil question

Man, talk about quick to jump, I ment regular oils that were not advertised as synthetic.<br /><br />I definatly stand corrected on this one, I do know that the motocraft is, and I guess it says so on the bottle, evidently most are not. I wouldnt use one that wasnt. When I said that they were showing some good #s, I was reffering to the motocraft, I do know that the Valvoline isnt showing as good.

On to this oil thing a little late, there is another function of oil that I didn't see mentioned. It also helps cool the engine, the thinner oil starts lubricating quicker on cold starts and the thinner oil flying around quickly helps cool the hot spots.

LD, This is a test to see how many miles I can get by changing at around 2000.<br />I've done an Oil analysis (sp?) every 3rd oil change before I add the cleaner/solvent. silica is almost non-existant and metals are extremely low.

Re: motor oil for hot climate

I know I won't because as I was playing in the Garage this am, my 2-1/2 yr old boy snuck out the front door and took a little walk.....needless to say, the cops came to the house asking me to come pick up my kid at the PD.<br />Wife is working 30 miles from home today and when I called her and told her what happened...........well, I think you can imagine, so the truck could very possibly out-live me........easily.
