Hi,

I have a 1987 (Toyota truck) with a 22RET/ RTE (factory turbo) that calls for SF/CC 10W-40 oil. I had a cam shaft failure, while running Castrol Syntec synthetic oil recently (in 2001). I think it was 5W-50. I was changing the oil and filter every ~3,000 miles. The last time I blew the turbo, the rebuilder recommended I use a 5W-40 oil...

What are my best choices (cost less than $25 per gallon):
---- The temperature here is between -10 and 110F (normally its 30-90F).
---- This engine has overhead cam, that the rocker arms ride (slide) directly on the camshaft.

My last OC was with Eneos 5W-40 Synthetic oil. Often I use whatever synthetic oil is on sale.

I used to live not too far from you and I dont think I ever seen it get to -10

I would say m1 tdt 5w40 would be a good fit.

High ZDDP dual rated HDEO xW40 in CI4/CJ4, avoid SN/SM PCMO.

I doubt the viscosity had anything to do with the cam failure, i would run as someone else mentioned M1 5W-40 TDT or Shell Rotella T6 5W-40.
Even a 15W-40 Conventional HDEO would do like Rotella, Delo 400.
If that engine is a flat tappet camshaft engine, then it might have been a low ZDDP oil that wiped it out, any of these oils i have mentioned have fairly high concentrations of Zddp.

Agree with the diesel oil recommendations.. 15W40 would do fine in this engine. But one of the 5W40 diesel oils would work great as well if you prefer synthetic.

I believe Valvoline MC oil meets SF/SG spec and it can be had for $3 per quart.

Comes in 10w40 and 20w50 flavors

Rotella t4,5,6 can be had cheaply at Walmart and is designed around diesel turbo applications

As the owner of several 22RE powered trucks I'm jealous of your factory turbo truck. I've always wanted one. I've never had a camshaft failure in a 22RE Toyota, ever, with a cumulative mileage between all the ones I currently own and have owned in the past of over 1.5 million miles. However when working in a machine shop I did see a few failures of aftermarket camshafts that were improperly heat treated.

My current daily driver is an 87 4Runner, I removed the original camshaft at 277,000 miles and installed an RV cam that's been in the truck ever since. I'm now at 330,600 miles with no issues. I haven't run anything fancy for oils on the original or replacement camshaft.

For your application and relatively mild overall temperatures I would run a 15w40 diesel oil or a 0/5w40 synthetic diesel oil if you're concerned about getting closer to the original API addative levels. Hard to go wrong with either one.

I had an 86 Turbo. Still miss that truck. I ran Rotella 5w-40 in mine and it seemed to do fine.

Hi everyone.

Thanks for the input. I'm not up with the abbreviations of the oil types. There no walmart near me.
What about, Lucas Long Drain Truck Oil 10297?

I think the Rotella will be what I'll use.

The temperature spread is based in where else I might go. It does get down to 10 to 20F on occasions here. The turbo re-manufacture felt that 10W or 15W was too thick for a turbo.

Nice Toyota Carj

So run a 5w40 HDEO

Hi Carj,

Nice Toy. And I see your an HAM too, me too...
