i think what 10W40 is not good for our engine, if I'm correct manual prescribes ..W50, so better use this or more and you will have better protection and higher viscosity in high temp situations.

We have 10w40 in our cars. . It's suppose to hit over 25 degrees celsius up here in Vancouver this summer though. Will 10w40 still be ok?

With Synthetic or semi-synthetic you can drop 1-2 weights for a given temp range and not worry. It is much more stable.

Which I think is part of the whole leak myth. Many when going synthetic change to much thinner oil.

I have run 10w30from 0 F. (-17 C.) up to about 105 F. (40deg. C.) without problems. I would not try that on dino though.
Dino I use 10w30 in winter, 10w40 in summer (same temp range as above).

I've been using 10w40 w/o any problems. It doesn't get as hot up here (pacific northwest) than it does down in the southern parts

.

Thanks for the answer sheepdog.

Mobile 1 10w-30

I used to use amsoil in my turbo vehicles, Motul is really the best though.

It just depends on how much money you want to spend, the m42 will last forever with synthetic every 3k miles.

You may want to take a look at this site if you are changing every 3000 miles, read the first section and then scroll to the last section titled "Interpreting wear metals".

Ford and Conoco, as well as this sites testing has shown the MOST wear occurs in the first 3000 miles after an oil change. You are doing more harm than good, especially with Mobil 1.

How often should we be changing oil?
