Oil Recommendation - 64 Chevy 283

[HondOtaChOrd]

If that's the case there is no reason to go any thicker than 10w30. Interesting that it has a spin on filter. Used to be able to buy the aftermarket kit to convert it to a spin on.

Thanks for the info. Currently it has Shell Rotella T5 15w40. I also bought some Castrol Classic 20W-50... Too thick?

What 10w30 would you recommend?

Is this ok for "regular"driving?

Yes it's OK but I would't have one for regular driving. Puts too much stress and waste of energy on a street engine. Especially in the grade oils you are considering.

Which oil do you recommend then?

When I worked on them in 1964, we used 10w40 summer and 10w30 winter. Typically Quaker state or pennzoil. Enjoy!!!

See my post #38 and zogg's post #64.

Also note I'm not a fan of using HDEO oil in gasoline engines. There are plenty of PCMO's to choose from.

Just curious why don't you like HDEO in gas engines? I tried it because so many recommend it here and the detergent is supposedly better at cleaning.

Pennzoil is burnt in my mind as "bad" because my dads old engine builder friend told him decades ago Pennzoil leads to dirty motors. Many on BITOG speak highly of Pennzoil so this must not be true anymore.

Fram 30 series. PH, TG, XG. The spin on filters came in in 1968 as I recall.
You may have a different engine?

Anyone still saying stuff like that is just talking out their arse. More like 40 years ago oil wasn't as good and sludge was much more likely to occur in vehicles that were neglected and/or had a faulty pcv system.
Nowadays no oil is going to be prone to sludge unless you have an internal coolant leak, faulty pcv, or neglect oil changes, or any combination of those 3.

Quaker State All Mileage synthetic blend or full synthetic? Both 10w30 all mileage is $3 cheaper at Walmart @zogg

This urban myth has probably been covered here a hundred times. Pennzoil does not lead to dirty motors.

Is the old tale full synthetic causes leaks in classic cars not true?

It was back when synthetics started to appear on the market.

PAOs, have a tendency to shrink seals and therefore cause leaks, however they figured out that for example adding x amount of Ester to that PAO was effective to prevent seals shrinking, since Esters have the opposite effect, they have a tendency to swell seals.

Nowadays the vast majority of so called synthetic oils are Group 3 HC oils ( except in Germany ) which are just very highly refined conventional oils, this problem is non existent.

Plus many oils sold in Germany as well.

Severe hydrocracking is far from just “highly refined conventional” oil.

But in Germany they can't be called Fully synthetic, but rather HC-Synthetic.

I'm not saying modern HC oils are bad, they are definitely not, but in essence the only difference between a Group II conventional base and a Group III ( excluding GTL ofcourse ) is the degree of Hydrotreating / Hydrocracking.

Please do correct me if i'm wrong.

 

[kschachn]

Well hydrotreating and hydrocracking are not the same. One is essentially as you say “highly refined” but the other one is reforming and reduces the molecular weight of the feedstock. Hence the one being synthesis and the other one not.

It’s not a degree of processing but rather a fundamental difference in what is happening with the molecules.
