Which cars specify 10W-40?

[Merkava_4]

I know that there's some Nissan's and Hyundai's that ALLOW 10W-40 under certain circumstances, but has there ever been a car in the history of automobiles that has ever specified 10W-40 and 10W-40 only? Just curious.

RX7s recommended 10w-40 year round but also had temperature criteria for other weight oils. I run nothing but 10w-40 in my 91 RX7 convertible and have no problems after 29k miles.

Let me guess, under cold temperatures right? I wonder if there's ever been a car maker that has specified 10W-40 and only 10W-40 and nothing but 10W-40, so help me ______.

IIRC, my 1981 Honda Accord owners manual only allowed 10w30 up to something like 90*F and allowed 10w40 across all ranges.

I used Pennzoil 10w40 and never had a problem for 160,000 miles.

I am sometimes surprised to see my Volvos state 15w40 instead of 10w40 as the high side for grades. Going from 5w3-, 10w30 to 15w40 seems strange when the natural progression to 10w40 seems so normal.

I will be using 10w40 Maxlife next OCI for both my Volvos and presume it will be a great choice.

That's interesting; I wonder if it's because the 10W-30's of the day were only good up until 90 degrees Fahrenheit.

My BMW 540i (1999) suggests 15w-40 if using conventional oil.

Peugeot 405Mi16 specifies 10W-40

Ah Hah! I knew there was one out there somewhere.

My 2007 Subaru 2.5 H4 NA shows 10w-30 and 10w-40 from 0 degrees F to over 100 degrees F.

If the vehicle is used in desert areas, in area with very high temps or HD apps, use 30wt, 40wt, 10w-50, 20w-40 or 20w-50.

They recommend 5w-30 for all temps and its preferred.

My 2002 Land Rover Discovery Spec's 10W-40

JBRIII, you beat me to it. On my 2002 Land Rover Disco's manual, turn to the front quick reference and it specs 10W40. Turn to the more detailed version inside the manual and it lists different weights for temp extremes.

My brother's Alfa 166 calls for 10W-40 only. He was hesitant to use some 5W-40 I gave him for top off oil, I told him he should be fine with the 5W-40.

XXw-40 is mainly used in diesels and motorcycles. Most gas cars and trucks call out "energy conserving" oils of XXw-30 and XXw-20.

However there are some VW's calling for it too XXw-40. 5w-40 specifically, but Mobil now makes a 0w-40 for these models also. Just picked some up last night as a matter of fact.

My 88 suburu, it "allows" the 30w's but not for extended high speed travel.

Dont the VWs recommend 5w40 or 10w40 still?

The owner's manual of my mom's 2001 VW Golf (2.0 engine) shows 5w40 as being the preferred viscosity.

 

[Doc8404]

my Galant specs 5W-20 all the way to 20-W50!

 

[jbas]

Kia Sedona's (through 2006) with Hyundai 3.5L engine, at temps over 86F, require 10W-40 (or 10W-50(?), 15W-40 or 20W-50). Dealer recommends 10W-40 year round. I called the Kia 800 service number early on, and they also said use 10W-40.

IIRC, our Kia Sephia that we had a short time, spec'd 10w-40; as did our '85 Hyundai's.

My Mom's '85 BMW 325E spec's a 40wt and nothing less, as does our '01 diesel cummins.
