Mixing edge

[Ratsmow]

Does anyone mix motor oil. Using edge 10/60 at the moment but want to add half 0/40 with it to thin it down a bit. I find the 10/60 puts too much drag on the motor. Castrol tech said it would be fine to do but all I really need to use 0/40. I'm thinking this would be the best of both worlds, there both pao and castrols two best oils.
Has anyone tried this before?

Im starting to think the same mate. Im using 10w60 but i might change back to a 50 especially in the cold weather in Canberra and I have a front mounted oil cooler so the oil would stay cold for longer. I havnt tried 0w in a V8 used to run it in my turbo 4s before ok.

Drag? how so ? Increased fuel usage?
Anyway oil cap says 5/30 , it'l be fine , more then enuff for Albury's cold mornings , 5/40 would be fine too,
even 10/60 is rated down to -20 deg C , but probably better for the hotter days.

Viscosity and friction are not necessarily related. Have a look at the link below and compare the 0W-40 to the 10W-60. It was in another post that I can't find at the moment. What leads you to believe that the oil causes more drag? Maybe at colder temps? I can't say I have ever seen any noticeable difference in economy with different weight (or brand) oils.

You might find some interesting reading in the thread I have linked below.

Xuv my engines only makes 240 rwk exhaust and tune only, so it's not as powerful as some. I had 10/50 elf in prior and I noticed straight away after oil change the motor didn't spin up as quick and it uses 1-1.5 litres per hundred, so I can only assume it's from the oil. My engine has only got 28000 ks on it. By the way I only use it on decent country runs, no traffic, 100ks an hour most of the time so my fuel usage is accurate. Make of it what you will but these are the facts. I can only assume in a less powerful engine the spin up speed and fuel consumption becomes a factor.

Woodchukka what about hths, surlely that has to be a factor in a less powerful engine. It may not be noticeable if you have 300 rwk but 240 is not 300 so I believe it's noticeable with less power. What do you think.

I'd say it's a crock of shit. Parasitic losses within the same brand of oil... or any oil would be minimal at best as long as it's good quality.

Differences in 'seat of the pants' will be far more likely to be outside temperature, weight load and tyre depth / warmth.

This oil sounds too good to be true.......

Sorry post number 6 is 1-1.5 litres per hundred more in fuel .

We've done it with kart engines and I know the junior dragsters use a super light weight oil to gain every last hp.

Drain the oil and go back to what you were using. See if the fuel consumption comes back.

Generally, my last consideration is fuel consumption, my first is protection.

I'd go back to elf but I can't get it in albury, pita. I'm not concerned about the fuel usage either really, just want my free spinning motor back. I don't want to change oil brand as I've always used castrol with good results. Had 3 cars with over 300000 ks on each with no oil related problems. That's good enough for me. Wish they made a 10/50 which is what I was hoping to achieve by mixing the two oils.

Just pull it down and knife-edge the crank.

The guys that blend and distribute this oil are in our club. From everything I have seen, their claims are true. Club members that are using it swear by it, would never use anything else. They even offer an 'oil analysis' service. Once you have done your oil change, you send in a sample and it will get independently tested. Report shows if there are any trace elements of metals that could indicate a problem with the engine, or petrol in the oil. That kinda thing.
Much longer intervals between oil changes are recommended too. I think (but dont quote me) it is 30,000k's for a road car and 50,000k's for a diesel truck.
So all in all if seems like pretty good stuff.
