Hey guys, I searched around and found that Mobil 1 10w30 oil was a favourite for the zed for alot of people. I had a gift voucher for Supercheap. So I was kinda stuck on getting something from them as my oil needs changing and cash is tight at the moment. This was the closest thing I could find that they had in stock. Any objections to it? I know it's different in by the fact it's 5w30 (for more colder weather i believe), but any issues? Cheers, James
IMO 5 is a little too thin for my liking. You MAY find you will get some oil leaks pop their head up. Personally I use 10-40 (i think, id need to check to be sure)
damn so i should of gone the 10w40 over this one. I saw it and thought this was closer, I saw someone saying (not this forum) that they use a 5w30, prob was America though :/
Agree with Black Beast a 10w30 seems thin. A 10w40 or thicker (let's face it these cars are getting on) would be the way to go.
When I first got my car I used Castrol edge 10w-60, but because it is a light weight full synthetic it really made the front seal leak worse. After some research I decided on Castrol GTX 20w-50 , its full mineral so its (arguably) better for older engines like ours, and the best part, only $15 for 5L !!
I recently tried Castrol Edge 25W-50, as our climate in Central Queensland is outrageously HOT & it came up trumps over anything I have tried before including Royal Purple. Engine runs quieter, smoother, cooler & oil pressure has increased dramatically. Will probably use 20W-50 in winter but finally it's good to find an oil for the Z I am actually happy with, Penrite was terrible for me in our climate.
Too thin unless it winter time in canberra or Mt fujiama and you stop start a lot You can get lifter tick with it as it will run off the lifters/cams very easily its a good oil though - just the wrong rating for Z's in oz 10W + is really the minimum that you need anywhere in Australia Supercheap sells penrite full synth 10W - 40 - (everyday use) that will stop lifter tick and give good penetration and will suit stop /start driving (wear the most wear occurs) Of course if your driving it hard you may want to increase the latter rating to 50/60/70 etc (eg 10W 70) or if you drive very long trips between starts or the motor is worn a bit instead then a higher Winter rating like 15W - 40 or even 20W - 50 will be a better adjustment as it wont produce as much carbon when burning off making it dirty quicker and thicker oil can increase compression, the dowside with thicker oil is that you can lose a few hp as its harder to push thicker oil around but a higher latter rating (anywhere up to 50/60/70/80/ 90) can fix this (but at more dollars though) In summary - oil rating is allocated by temperature/ driving style (hard or easy on throttle) and whether you start and stop a lot or drive for long periods and whether the motor is worn and how trivially concerned you are about losing a few hp for a thicker oil - so only you can tell what oil you need! The only golden rule is to change oil and filter at 5,000klms regardless of whether synth/ blend or mineral based and never use other additives Getting magnets for your sump bolt and oil filter can be really good - you can see the gunk it holds when you change the oil (minute metal particles) - that means less wear and means that the magnets are well worth an investment! Dont worry - the oil you have got can be used to help flush out old black oil by tipping a cup or two in between oil changes to help make it clear before you put the good oil in, as the last thing you ever should do is use a flush agent unless its a stripped motor (will kill your next batch of oil and bearings as the oil will run off extremely quickly from the remnants of the flushing agent) If your oil is black - you are well overdue for an oil change - as a guide mine is always clear or at very least, medium clear brown at 5,000klms - but my motor also has good compression on all cylinders as well You can always tell if you have the right oil by - looking at the exhaust straight after starting and seeing a small amount of smoke and when its warmed up seeing no smoke, but then when you accelerate heavy under load you get a slight puff of smoke - that will tell you your running the right oil! - you should have spark plugs that indicate it as a result - light black with no deposits. Now go and get the good oil and happy motoring!
This is worthy of a read, its got some good info that goes against what most traditionally think about oil. http://www.supramania.com/aehaas/
This should be most people's source for good oil/filter info. http://www.bobisth***lguy.com/forums/ubbthreads.php?ubb=cfrm
