buy australian owned / made............Penrite
 
i work at autobarn and tryed some of the penrite usa imported gt racing series oil in my clevo 25/50w and it was sought of noisy and didnt run as smooth and i have just put hpr50 in to try get over an oil pressure problem and found that the motor ran alot smoother on the penrite and one of the older guys that i work with said he wouldnt sell anyone anything else b8ut penrite he has always had nothin but good fortunes with it

Thats right i know a lot of people or swear by Penrite. They've got my vote anyhow. The penzoil seemed alright but the penrite just seems that bit better, probably only marginal. I think the penrite HPR series is the highest quality oil you can get unless you go to the synthetic stuff. I was shown how you can tell, theres something on the bottle. Can't remember now.
 
I gave penrite a call just to check if I should be using HPR15 in my motor. I read a couple people in this post use HPR50.
Penrite say unless the motor is very well run-in and almost run out, it shouldn't be using HPR50. its too thick and puts more load on pumps than is needed on a newer motor. They recommend HPR15 and HPR30 on motors with a couple thou km's already done.

so why are you guys like brenx running HPR50? it would raise oil pressure, but i think it would have more of a negative result/effect.
 
Because we like having decent oil pressure and no engine wear. As HPR50 it's designed for -:

A 40-70 extra high viscosity petrol engine oil which meets API SL performance levels. Non friction modified. Suitable for use in large six and eight cylinder engines and those subjected to heavy load situations such as caravan, boat towing or competition. Equally suitable for large engined vehicles suffering oil consumption problems. To be used with caution in extreme cold.

[edit]I wouldn't run a standard type oil in a modified engine when racing or driving long distances.

HRP 15:

An SAE 15W-60 semi-synthetic engine oil formulated for use in latest technology multivalve- multicam computer managed or conventional engines. Exceeds API SL/CF performance levels and those of ACEA A3/B3. Non friction modified. Primarily intended for: · Petrol fuelled cars (including turbocharged,\'); · LPG fuelled cars. Can also be used in petrol and LPG fuelled four wheel drive recreational and light commercial vehicles (up to 3.5 t GVM) and diesel fuelled cars (including turbocharged). Meets the lubrication requirements of Porsche. For diesel fuelled four wheel drive recreational and light commercial vehicles, our primary recommendation is HPR Diesel 20W-60 or for new vehicles subjected to light work or for use in extreme cold, HPR Diesel Light 15W-40.

HPR 30:

High viscosity, non friction modified SAE 20W-60 oil formulated for use in conventional engines and latest multivalve, multicam, computer managed engines operating under a high load environment. Exceeds the requirements of API SL/CF performance levels and those of ACEA A3/B3. Meets the lubrication requirements of Porsche. Non friction modified. Ideal for use in- · Leaded and unleaded, petrol engined cars and four wheel drive recreational vehicles. · Petrol and non-turbocharged diesel engined light commercial vehicles (up to 3.5 t GVM,'); Not recommended in diesel engined 4WD recreational vehicles, use HPR Diesel oils.

Penrite actually recommends HPR40 for a 351 cleveland. If dual fuel HPRGAS
 
The point most of you fella's are missing is , flat tappet engines need Zinc in the oil to prevent cam lobe wear and the bigger the cam the more wear , inc- heavier springs to made it worse . Minum requirements for flat tappet cammed engines are .011% zinc in the oil , now the oil companys had to lessen the zinc content because of damage to cat converters , hence roller camed engines in most unleaded cars (less cam wear) , Penrite oils that meet the .011 are HPR 30 , 40 , 50 and gas , most the Kendall range does also , 99% of the Shell's , BP's , Castrol's etc and Synthic's have .07% to .09% zinc in there oils and most of it isn't real Zinc either (artifically made zinc) This is why we are losing so many cam lobes now a days in early engines . Zinc is a anti scuff/wear for metal contact areas and is still heavly used in diesal oils (no cats to damage) l have argued with oil reps over this and when they come back after checking the facts and then say that the old style flat tappet cammed engines are such a small % of the market share now a days and goverments rules and regulations are forcing these changes apon them , so the best advice (if they will tell you , because l had a had time getting to the truth) is to find out whats in the oil you prefer and not what the sales person behind the counter is trying to sell you .

P.S Oils aint Oils anymore !

P.P.S l use HPR 15 in my T3-TE50 and F/Lane V8 Ghia and HPR 30 in the rest 351 ZD , Winsor power 929 Coupe , 85 IROC 5lt HO
 
I put in HPR50 last nite, and only raised the pressure at idle while hot. I used to have 12-15 pounds at idle, and i now have 20 pnds. It still maintains 45 pnds at full throttle, but on average stays up near 45 while cruising at slower speed at 60 km/h now.
Had Kendall before.
