pennzoil 10w-30 but I'd run 10w-40 in a higher milage KA

I run Mobil1 synthetic 15w-50 in my motor with a K&N filter

 

Last summer I worked at a quicklube and I will tell you I will NEVER use penzoil or quakerstate. It's only mobil or mobil 1 for me.

 

I run royal purple 10w30 in my car. I love the oil. The engine revs a bit faster, had a small power gain, and a slight increase in miladge. Damn good stuff if your willing to drop the money. I've never tried mobil one but I've heard nothing but good things.

 

I use Mobil 1 synthetic 5w-30 in my KA with 135k. That stuff is the sex.

 

What is the problem with Penzoil and Quakerstate? Just wondering what you have found/seen because I run Penzoil 10w-40 in my 155k KA24DE

 

We always joked that if you wanted your engine to blow up.....put some penzoil in it. Penzoil does more marketing than anything else and the quality is substantially lower than most. I've poured 5w20 in a motor and stood in awe as one quart was nearly black and the other was clear.... Some of the other manufacturers "errors" we're not allowed to say ...considering I still work there on breaks. To put it this way you can get a better product for the same $

 

Mobil1 10 30. Makes the lifters nice and loud:yummy

 

ok not to sound all cockie but dosent ka24de have a direct acting valvetrain other less saying doesnt the cams lobes pushvalve spring down hences no lifter unless your talking about a 12v ka24e

 

Theres still a hydraulic follower(a.k.a lifter) between the cam and the valves.

 

Bad nailed it on the head Hydraulic lifters chief, just like sr.

 

SRs actually have rocker arms.KA24DE is direct cam on bucket.I dont see what's so "hydraulic" about the valvetrain.On the KA24E it's pretty obvious

 

Never said the valvetrains were the same.I know sr has rocker arms,,with hydraulic lash adjusters. Whats so not hydraulic about that/. Both designs are considered hydraulic not mechanical.

 

Apparently these guys who sell only items they deem the best for 240's think NEO have the best oils.

What do you think?

Have you pulled the cams out of a Ka24de? That "bucket" is a hydraulic lifter. Its not a solid follower that use shims to set the lash. The follower expands with oil pressure to take up the lash, hence the term hydraulic.

Oh yeah, and back on topic, I use 15w50 Mobil1 exclusively.

sorry to bring back the dead...but the de is a shim in bucket style valve train. there is nothing hydraulic that I can see about it. It goes something like this
cam lobe
shim
bucket
retainer
spring
valve

the shim is what takes up lash, use different shims to add or take away tolerance. You can buy different thickness shims from nissan.

If you pull the cams out, and you pull the bucket out, and then pull the shim off the top of the bucket...there isnt any oil passages. I cant see how this is hydraulically adjusted.

What I am missing about this? please someone fill me in

 

If you look in the owners manual you will find that Nissan recommends 5w-30.
I've had my oil changed at a Nissan dealer in two different states and they both used 5w-30 Mobil non-synthetic.

this is exactly correct.. it's a shim/bucket style valve train.. and if you wanna argue that the valve shims adjust themselves hydraulicly, I'll give you the # to the machine shop that's got my head right now.. SHIMS ARE USED TO ADJUST VALVE LASH ON THE KA24DE HEAD!!

 

thank you Kenny. I knew I wasnt crazy. The voices in my head told me so!!

no problem..

1bad240SX wasn't entirely wrong.. but what he didn't get right was when he said that it uses oil preasure to move the buckets up to adjust valve lash.. which may be true on SRs, but on the KA it is not.. valve lash is adjusted by different sized shims.. if it was hydraulic, I'd have had my head back today, instead of having to wait untill they finish my lash adjustment after just doing some mill work, resurfacing, and doing a valve job.. he said lash adjustment takes a while because you have to install, and remove the cams several times to ensure they've got the right size shims in each bucket.

 

Either way I still use the trusty ol speedway "engine lube" no really though mobile 1 is great oil otherwise they wouldnt put it in corvettes and vipers from the factory

 

Recently bought an 89 240sx coupe. Doesn't have mods or anything. Has 229k miles though and I'm trying to make it last by the end of summer. Just wanting to know what oil I should use for its longest life for now. Nothing's wrong with it but I am kinda beating on it(even though I shouldn't lol) it's just a fun car to drive. And I live in Texas.

 

says on the owners maunel but im assuming your engine is old and beat up and prob leaking a little so i would run some thicker oil im running Valvoline 10w40 full sythetic on my 203k KA and it runs amazing but i dont think the brand matters that much id pay more attention to the SAE viscosity gradings

 

Holy thread from the dead. Almost 11 years...
