ow-40 like water? lol...


LOL seems everytime a 20wt oil is mentioned along with a 30wt the thick vs. thin wars begin. If it were my car and I was worried about 100* weather then I would run the suggested 30wt for the summer and run the 20wt in the winter. In reality the 20wt would work well year round. YMMV

20wt, thats thinner than water!!!!! For the summer I'll use a straight 50 weight, and for the winter I'll use a 20w-60, becuase you take 20-60 and you get -40...and it gets about that cold where I live....

jdblya - We can't determine an admission that 10-30 is better because of the manual's statements. That is a real stretch.

It appears that for 98% of driving, the 5-20 is better. Maybe 99% in your area.

0W-30 is a fine choice, perfectly safe.

3+ UOA's in a row with the same oil every time would be the only way to compare the two weights.

For whatever reason, I just feel more comfortable with the Amsoil 0w30 oil over the 5w20. It may be that when I look at the specs, it offers better protection, or it just be that 30w is stuck in everyones head (or at least mine, growing up everything was 30w). All I know is that I drive the car only in the summer, and drive it pretty hard and it just gives me piece of mind.

Also, it says "for optimal fuel economy and cold starting". 1% 2% Better fuel economy would be extremely optimistic. Not to mention, that there is prob less dray with a high quality 0w30 than there is in a conventional 5w20. Plus, I'm still pretty sure that 0w flows better on cold starting than does 5w

Not to insult you in any way but how do you know that?


Got it from a well-respected person who knows what he's talking about, based on things other than opinions or guesses.

0w's are ideal because they run the closest to operating temp when cooled. 90% of engine wear happens at start-up. Auto mans would run it but its only made in the syn flavor. $$$

Good to know there's so many posters, some new and psychic, who know more than the car manfacturers.


If they knew so much, then perhaps there wouldn't be recall notices would there?

No insult intended either, but since you provide no proof or statistics (I.E. Name or "things based on"), it would seem your posting is as heresay as the rest of the opinions. please show us...
