Which oil should I use next?

[Clement]

Well, since finding this board, I have amassed a small menagerie of oils. Now I'm having a hard time deciding what to use next! Here's what I have on hand:
Chevron Supreme 5w30 & 10w30
Valvoline MaxLife 5w30 & 10w30
Pennzoil 5w30 & 10w30
Mobil DCP Syn Blend 10w30
Supertech Full Synthetic 5w30

All are gf-3

The car is a 2002 Hyundai Accent, 1.6L, with a 3.5qt sump. The car has 49K, and I drive it fairly hard but not abusively. The OCI is 3000 - 3750 miles for warranty purposes. During the upcoming OCI, temps will be in the low teens to mid 80s (F), although more of the former than the latter.

I'm leaning towards the Chevron Supreme 5w30, just because.

What do you think?

Good choice. Problem is wiith the GF-4's coming in folks will be sorry they stockpiled.

Okay, rummaging thru one's oil stash is a fun thing for Bitog members. My suggestion is Pennzoil 10w30 for the temps you indicated.

Pennzoil 10w30, 10.5 cSt @ 100C, is in the group of 10w30's that run to the light end of the SAE viscosity scale. Cold starts with temps in the teens are no problem.

Why do you say that Al? I haven't seen anything so far which indicates to me that the GF-4 oils are going to be any better. In my case, I stockpile because I'm worried GC Syntec 0w30 will turn back into USA Syntec 0w30 and won't be as good.

I wonder why so many car makers recommend 5w30.

DITTO.....^^^^^^^^^^^^

With a cooler season coming up, I would use either Pennzoil or Chev in 5w30 and save the 10w30 for when it warms up again. After all the reg dino is consumed, start on the synthetic with extended drain, and after that is used up, try out the Valvoline MaxLife stuff

Back to my rant on many 10w30's & 5w30'S are the same oil:

(Note: I will be back on my meds soon & leave this subject alone!)

code:

---

1. 68 cSt @ 40C, 10.2 cSt @ 100C

2. 67 cSt @ 40C, 10.5 cSt @ 100C

3. 65 cSt @ 40C, 10.7 cSt @ 100C

4. 66 cSt @ 40C, 11.1 cSt @ 100C

Here are the oils per the above viscosity data:

1. Citgo SuperGard 10w30
2. Pennzoil 10w30
3. TropArtic 5w30 (GF-3 version)
4. Motorcraft 5w30

Too often, 5w30 is commonly viewed as being a "thinner oil" than 10w30 and this is not the case when looking at the spec's for individual brands of oil.

Viscosities are very similar. The 10w30's are more shear resistant. The 5w30's will have better cold start performance at below zero temps.

I went with the Chevron Supreme 5w30. I'll change it again in another couple of months and we'll see what happens then.

i was wondering wich oil is thiner (10w30) castrol,pennzoil,motorcraft,valvoline?i do not list chevron cause i cant findit here in n.c. so those oils are my choices and i think are the top oils too right?(conventional oils)with winter coming i would like to keep using a 10w30 in my f150 4.6 thatswhy im asking wich one is the lightest tks.

 

[Blue99]

aztec12 - Here are the viscosity #'s for the oils you listed, minus Castrol, plus Chevron.

code:

---

Pennzoil 10w30 67 cSt @ 40C, 10.5 cSt @ 100C

Valvoline 10w30 71 cSt @ 40C, 10.5 cSt @ 100C

Motorcraft 10w30 72 cSt @ 40C, 10.8 cSt @ 100C

Chevron 10w30 73 cSt @ 40C, 10.8 cSt @ 100C

The Valvoline data is for All-Climate.

I added Chevron Supreme to aid in highlighting Pennzoil 10w30 as being towards the low end of the popular, OTC conventional 10w30 viscosities.

These are the differencs per the data, however, since these are all API Starburst energy conserving oils, actual performance will be very similar.

That little 1.6 will thank you for the 5w30 when it gets cold .

There are properties in these oils that data sheets don't show .
