Are you sure you can't mix weights? I know its not the best thing to do, but its not exactly harmful for the engine, as far as I know.

I'd strain and reuse my hpr15 before using magnatec... But ur car ur call. If u do keep running it, definately keep flushing every change and change Regularly!

Yeah I've been talking to some people and decided that 5W40 is probs not worth the risk. Since you seem to be an advocate for Penrite. I'm thinking of trying the following. Both these are 10W40 full synthetics.

Everyday Full Synthetic 10W40 - http://www.penriteoil.com.au/engineo...id_products=27
Racing 10 - http://www.penriteoil.com.au/engineo...d_products=277

Is there honestly a difference between the two? Racing 10 is about $35 more at supercheap auto. But at the end of the day they're both 10W40 full synthetic.

While they are both good, they are not the same.

The cheaper "full synthetic" is a group 3 base oil, it's made from crude oil, Group III base oils are sometimes described as synthesized hydrocarbons, or hydrocracked, it's fake synthetic so to speak.

Group 4 base oils are polyalphaolefins (PAOs)
Group 5 base oils are classified as all other non-petroleum oils, such as polyester and esters.

thanks fredoops. so as u can see not all oils are created equal. for your purposes Hpr10 would do the job well. you could run racing if you really want but as the name suggests this is designed for race cars, (main difference is that it is shear free) even then its not a must i know quite a few people running hpr products in their dedicated track cars with great success. you could also run the everyday 10w40 if you wanna save a bit more but as previously stated its barely a full synthetic, in fact its only in the the past year that it has become considered a 'full synthetic'.

personally I'd suggest you jump on their website and look into the products. they have quite indepth info on all their products as well as good info on what everything means.

Its odd that people are willing to use full synth and spend approx. $60 per oil change for general dailys like gsi,civics etc. yet run the cheapest rda brakes,china tyres,taiwanese suspensions..

maybe its just me but that doesnt sound kosher

as long as my vtek goes hard its kosher mate

yer dat booo BAAAA

Also don't forget that $9 Ryco oil filter as a K&N filter is a waste of money hahaha

Thanks for that, much appreciated. So the everyday full synthetic is just a marketing gimmick. I won't be using that anytime soon haha. So you think HPR 10 would be best? Would there be a big difference in running a 10W50 instead of 10W40. I prefer not to thicken the oil up, unnecessarily.
