Who is using 10w-30?

[Elkins45]

I’ve owned a bunch of different vehicles over the years and none of them have ever recommended 10w-30. The only engine I own with a 10w-30 recommendation is a Briggs and Stratton V-twin mower engine. Who is using all the 10w-30?

My 1999 Integra

My AP1 S2000 calls for it, and I run Castrol Edge 10W-30 in it. I’m in a temperate / hot climate. I’m sure I could run something more modern.

Many new diesels use 10w-30.

The 2002 Wrangler 4.0 specs 10w-30. I'm using Pennzoil HM 10w-30 for a slight rear main seal weep.

I have been running Mobil Delvac 1300 10w30 in a few different cars. Next OC, I am going to run it in my LX570. I may start running it in everything.

I have used it. Anything that specs 5w-30 can use 10W-30 in moderate weather.

Given 5W-30 became common in the mid 80's you would likely need to go back a long ways to find something that actually specifies it.

Toyota says I can use it for my 2.5 Dynamic Force but only in Australia.

I have a couple of jugs I bought on sale. I figured I would eventually use them in dad’s 98 Chevy. It’s driven so little the oil I use is almost inconsequential.

I use it in my Honda powered lawnmowers it's what it's called for. My beater Pontiac G6 2.4 I use a dino it loses less oil then a synthetic especially in 5w30. I'm going 10w40 High Mileage conventional next only because I got 10 qts for $5

The last time I used 10w-30 was way back in 2001 when I had a 97 Grand Prix GTP with the 3.8 supercharged engine. GM recommended 10w-30 for that engine.

The last vehicle I have owned that called for 10w-30 was a 2001 Volvo V70XC. The engine went 278k, mostly on 10w-30 and was still going strong when I got rid of it. I did dabble with Mobil 1 0w-40 for the last few years when towing with it.

10w-30 remains as my go to oil for the OPE after having dabbled with both 5w-40 and 15w-40 in some applications.

My jeep . Book says 10w30 above 0F and 5w30 below 0F no exception.

Can you actually still buy that stuff?

At the risk of sounding super young, I've only had cars that recommended 5w30 or 0w20, starting with a 3800-powered Buick in 2015 (5w30 on the cap - a few years too late for GM to call for 10w30), including our old Sienna which still calls for the same.
I think I missed the common 10w30 recommendation era in cars by about 10 years. That said, I do run it in mowers/pressure washers, and the like.

 

[BC1]

No I do not use thin oil.

I'm using this stuff in my 05 TJ Wrangler with the 4.0L engine. Seems to like it just fine.

In my Champion generator

My daughter Ford Fusion calls for 5w-20 but shes a leaker! So she has 10w-30 maxlife in her now. Will go to 5w-30 in late fall.

I just picked up a 6 quart box of Havoline High Mileage syn blend 10W-30 to add to the stockpile for the Mazda in my sig. It calls for 5W-20 but I've ran Mobil 1 Full Synthetic 0w40 and Quaker State Euro 5W-40 the last two oci's. Thicker stuff don't bother it(or me)
