5W30 vs 5W40 oil: When to use a 40 rating?
Somebody
I have a 2002 Camry LE V6 and currently use regular "dino" 5W30 grade from
the Toyota Canada Dealership. My vehicle has about 4,500 KM on it now.
I plan on switching to Synthetic at the 8,000 KM (5,000 mile) interval.
Toyota's Fully Synthetic oil, which is made by Esso, is a 5W30 grade. I
have seen ratings of 5W40 and 0W40 grade oils. Since I am in Toronto,
Canada, is 5W30 grade oil sufficient or should I go with something of a
different grade. Will switching grades from 5W30 to something else void my
warranty?
Thanks

All of those grades are suitable and great for your vehicle. I would
favour the 5W40, but that is a personal choice. Each is suitable for a
very wide range of ambient temperatures.

5w-30 oil. Good deal on switching to the esso synthetic, i think you
notice the less strain on the starter. Improved gas milage, smoother
and much quieter engine.
I read the longer spread between the numbers is not good. A 5w-20 or
5w-30 would be best. Im using the 5w-30 in my new corolla and sure
plan to stay with it for the life of the car. I will also switch to
synthetic after a couple 5000 mile oil changes. Here that same oil is
under the mobil one label. Look for the super syn name it may be on
that esso synthetic container. Its the latest in oil technology.
Not sure on the warranty. I do know if there is any engine failure
the oil is lab tested first thing. Personally I would just use the
5w-30 and not worry about the warranty.

Well that settles it. If Huw favors 5W-40, I would definitely stick with
5W-30.
5W-30 is the proper viscosity for you vehicle and a full synthetic 5W-30
like Mobil 1 provides way more engine protection against thermal breakdown
than you need (although I would definitely recommend a full synthetic).
If possible, I would use Mobil 1 instead of Esso. Mobil 1 is distributed by
Esso (Imperial Oil) in Canada. Neither Esso nor Mobil 1 sells a 5W-40 full
synthetic oil in North America.

0W40 is undoubtedly the best grade of oil but it is hardly cost
effective for normal use at normal service intervals. The 0W part is a
distinct advantage for cold starts while it never gets thinner at high
temperatures than a 40 weight oil. In fact it is so viscosity stabile
that it probably remains at a pretty remarkably consistent *absolute*
viscosity whether it is cold or very hot. In other words it is about
as thin at 0C as it is at 100C plus. This may be hard for maff to
grasp cosidering the difficulty he has with the general concept of
viscosity.

It does not matter a jot what brand is used, the difference being
marginal. What matters is the standards the oil meets and these may
vary even within a synthetic brand. Mobil 1 has several different
products which may seem identical apart from viscosity, but believe
me, some are very much better than others.
Frankly synthetic is overkill for most Toyota engines at US service
intervals. But hey, it's your money and if you want the best, why not.
Even the lowest spec Mobil 1 is great unless you push the envelope.

Typical Properties
Mobil 1 0W-40
Product Code 97E494
Test Method
SAE Grade 0W-40
Viscosity ASTM D445
cSt at 40oC 71
cSt at 100oC 13.5
Viscosity Index ASTM D2270 196
Viscosity after shear,
cSt at 100oC 13.4
If I read this table right, mobil 1 0W-40 goes from 71 to 13.5 cSt as it
warms from 40C to 100C. That sounds like a large change, even though most
other oils change even more.

From experience, you have to keep it simple here Jerry. The important
thing is "even though most other oils change even more"
Some cannot fathom that this grade meets standards that the others
cannot meet.

Now I've got a few moments I'll expand.
From a human perspective which we can all understand, 0w/40 comes out
of the can with a weight which approximates to horse piss thin. When
at operating temperature in an engine it remains with the approximate
viscosity of horse piss.
A 15w/40 oil on the other hand comes out of the can like the tomato
sauce in a cheap tin of baked beans. At operating temperature it thins
down to the same horse piss weight as the 0W/40.
Now we can all relate to their relative viscosity.

ROFLMAO!
Ya know huw, I knew you had some good blood in ya!
Funny, but it really brings the numbers home.
I love it!
