    HI
    Building a 400 chev
    I`m looking for high zinc oil with Low detergent

    Engine block and oil pump
    Eg SHP chev recommends standard flow pump . Upgraded Pressure spring canbe used
    Oil pump Mellings SELECT SERIES - few mods for better performance

    Cam, Flat tappet vs Hyd roller ??

    Revs your turning above 6,500??

    special fuels ??
    Running rich 12:1 AFR will need more oil changes and u might use a lesser oil quality

    10w/15W -40/50
    either semi syn to full synthetic
    Synthetic flows better at cold temps
    Caution there are some really shit quality oils around eg some barely qualify as part syn or full syn
    Better IMO syn is ester POA oil type
    Castrol / BP took Mobil to court about definition of synthetic oil
    All the usual brands Penrite ,Mobil 1 , Redline , Royal Purple , Amsoil Anything that meets criteria !!

    Many oils cross over and oil weights canbe different country to country .
    I have used 10w/40 Mobil m/cycle oil in many a car B4.

    Running in oil is different very basic mineral and cabe a mono grade

    Today's oils are all good. It boils down to personal choice. I like & use Penrite, Aussie owned & made.

    The big 4 still offer better quality oils then the Aussies can. I was a penrite man but have seen the light lol. Pay attention to viscosity indexes and TBN's. There is even documented results on bobtheoil or whatever that even the ULX doesn't stand up to Synpower full syn. That's one example. I've seen the results the big brands make on turbo cars as well like the barra. Cam type and run in will be variables though. Of course nearly all the exotic full/semi Syns are great oils as well if your keen to pay the cash.

    For flat tappet cams we use Lucas 30wt beak in then after that, Valvoline VR1 10w-40. We haven't lost a lobe in years since using the VR1 in fact we use it in all of our HP street engines.

    HI
    CAUTION
    Donot use any racing fluids as they may not have additives for a street vehicle. Engine oils and brake fluids mainly . Always check with maker. Always ask for a recommended change interval [most likely 5000kms or less][ask how long between oil changes ,some oils break down quickly eg 6- 12mths ]

    EG VR1 has been reformulated as once upon a time this was not usable in a street car.

    ## if u are running rich mixtures ,the xtra fuel will dilute oil quickly

    Yep Valvoline VR1 and Synpower are very underrated in Australia. Their the 2 I use depending on the motor.

    Circuit VK,

    What 'light' did you see that you claim stopped you using Penrite? In an OK Timken bearing test some years ago, first place was a tie: between Penrite syn & Royal Purple. Some really big name oils [ & expensive! ] like Redline & Mobil 1 did very very poorly.

    Penrite HPR30 in both my cars. My Buick is a daily that does 15,000 Ks per annum and it gets 1 oil change a year. Camaro only does 2-3,000 K's per annum but gets old changed every 6 months regardless. Neither rarely if ever need a top up, although Camaro uses a bit more than the Buick

    Sorry, I fail to see what a Timkin bearing test has to do with load carrying capacity and film strength that is all important in an internal combustion engine.

    Lucas 20/50 mineral flat tappet cams.
    Mobil 1 Delvac 5/40 roller cams.
    Penrite hpr30 with Lucas engine break in additive first hour on flat tappet cams.
    Works for me.

    AED,
    The Timken OK load test has EVERYTHING to do with loading bearing capacity. It measures the load the oil will support before the oil film is broken & metal-on-metal contact occurs.

    Nothing wrong with Aussie oils they can do the job for most with no problems. If you want the best though you may have to research and trial from there. If you are going to be leaning on an engine or have forced induction etc etc it pays to do the research.

    Apparently if you rely on the timken test shampoo is the best oil. Remember pert shampoo lol.
