Casterol 5w40 A3/B4

But I switched from Casterol 5w30 A5/B5 because I was getting this noise and temps are 30+ here. Prefer the protection over fuel economy

Mine didn’t like the castrol 5w40 when I used it years ago, you are better off with total 5w40 but not the energy version
 
The only thing is for european oils, castrol is the only oil I can get anywhere off the shelf and most affordable. in conversion, it costs me 22 english pounds, for 5 litres which is pretty good for quality stuff. Everything else in that bracket is driven towards north american oil specs. Unless I go for us here really exotic stuff like motul, liquid moly, ravenol etc. I am paying up to 54lbs for 5 litres.

Mobil is too loud. I could give Pennzoil a shot? Or just meet in the middle from exotic to quality and go for premium and get Shell T6 5w40.

Who knows....

Look on YouTube and search Peter tester oils, he tests loads of oils and I use total quartz 10w40 based on what the tests say and for my climate (south of England where it never goes below -10) but you may find something more locally available to you which comes good in the test? Where abouts are you located?
 
Canada, -20 winters plus 30 summers,

Never had an oil issue, 10w40 for -minus 10 seems heavy but I’ll take your word for it.

I feel better using 5w oils

If you like oils like myself, try lake speed jr. the oil geek on YouTube. He is pretty knowledgeable.

Not really it’s actually good until -20 although at the point I would use a 5w, here in the south west it’s very mild even in winter so completely different to up north in that regard, not sure if you can get it in Canada but the redline oil seems to come out really good on the tests but another thing is the oil filter, use genuine if you can

I use OEM. From my understanding the suppliers for Genuine. Redline I would say is up there with the best. Expensive. I put it in my 1965 396 BigBlock. Works really nice. Royal Purple is great but more driven to north American vehicle specs.
 
Maybe you're looking in the wrong place for the source of the thumping noise. What about the harmonic damper at the front of the crankshaft, when that's failing it can cause some strange noises.
 
Thank you for the tip, Just checked now, it’s tight. No play.

There is a small performance change in certain environments and I feel like it is the fuel pump. Again I am not very concerned because the truck has started up the same as the video since purchase. Will just let it be for now.

I have no fault codes or anything listed on the first post of the thread. The symptoms are not consistent so I am going to leave it for now. I get High volume, low volume, long duration, short duration thumps so I’ll let it be.

Fuel additives seem to help a bit. A motul specialist once told me they don’t put the same amount of cetane In diesel as they do in Europe. Possibly poor fuel?? my fuel additive package that I add has +7 points of cetane so perhaps lack of performance additives in our regular diesel
 
at this point I would use anything other than Castrol oil in your engine it’s known to be a load dog crap, change it for something decent,you will see a difference

How so? I have tried Mobil1 High Mileage Extended Performance which is basically top of top for quality where I am at (unless you go for Castrol Gold Bottle) and it was loud as hell. Unless I spend outrageous for quality Castrol is the best fit
