Going for an Oil Change

Getting the Castrol GTX High mileage engine oil for my 99 ex

what do u guys suggest ?
5W30 or 10W30 ?

Also any additives you would recommend ?

Thx

you should be running 10w30 if your motor is 100-120K+

10w30 is good for high mileage, but a thinner oil like 5w-30 is much better in winter. I would highly recommend using 5w-30 in the winter as it really helps reduce rough engine starts. I am using 5w30 synthetic right now and it was night and day during the winter when compared to 10w30.

5w-30 is better for winter. I use 10w30 all year all the time.

0W30 all year long

The Prophet

for all engines?? new and old??

Gallagher

50w30 or pure honey

pm me the year, make, model of the car, and I'll tell you.... by older, do you mean 1932 Model T, or 1989 Honda Civic?

Just a general note, pertinent to this discussion, which I think everyone understands anyhow ....

Engine oil viscosity is important and measured only at normal operating temperature, which is about 210 degrees F. (The "30" part of its viscosity.) All oil, when cooler than this, will thicken up. The 5W doesn't thicken up as fast as a 10W does, so at room temperature the 5W will be a little thinner than the 10W. This means, for the owner, that the engine will turn over easier in cold weather, with 5W than it will with 10W oil.

In any oil (syn or dyno), the 5w will turn over easier than 10w. The nature of the oil can also have a significance here. Synthetics (any brand) retain their fluidy at much colder temps than dino oils. Take a look at this oil study, and take note of the "pour points" for different brands of oil (keeping winter in mind). The pour point is the lowest temperature at which the oil will flow. Amsoil 10W30 has a pour point of -58 deg F; whereas Castrol GTX has a pour point of only -29 deg F. Amsoil TSO 0W30 has a pour point of - 65 deg F.

After a weekend of ice fishing in Tamagami this winter, what oil do you want in your car? At 40 or 50 below, lots of cars will have a serious challenge.

i have been using oem oil on both of my cars, one was old and one is new...never had problem in the winter! stick with what your manual says unless you have money to spend on these name brand almost the same/better as oem oils

imported_starboy869

OEM oil just relabeled from another manu. and of course stick Honda markup price on it. I highly doubt Honda has there own refinery.

For oil I would be only concerned with the grade, operation temps, and the API oil grade.

Just like cam said. -40 to -50 (these temps are more common in places like Winnipeg, etc)

chris_si98

**** if it was any colder than -15 my car would be staying in the garage and i'd carpool.

i stick with 5w30 in the winter time, always been fine for me.

imported_atif7x7

5W30 it is then for this winters

Thx all for the replies ..

Btw parts source is selling a Castrol GTX High mileage 5w30 jug for 11 bucks ... i knw some ppl think its a waste of money but hey at 11 bucks its still a steal

I get my Mobil 1 from Walmart in the USA. $20US/$24Cdn for regular $25US/$29Cdn for the extended Mobil 1

I think the cheapest I found Mobil 1 here is $38 @ CT?
