What brands of oil have people been using in their Sports?
I'm currently using Nulon 10W30 & very happy with it
I used Penrite 5W40 before that but think the viscosity was too thick

Shell helix ultra 5W40 (I think). So far so good. I like to have the higher top end to the range for hard use on a hot day.

I've been using the Mobil1, which is 5W-something (silver bottle, not the gold one).

Runs fine when new, but it appears to be burning off ever so slightly after 10,000kms. It's probably time I changed it as it appears to have thinned a bit.

I've previously run some high-end Motul stuff (I think it was $80 for the bottle) and that was fantastic even at the 15,000km point where I changed it..

Im running 10w40 gulf western with nulon E20engine treatment also useing a purolator oil filter ( part number PL 10241 ) serviced intervals every 10,000 ks , works extremely fine , 5w oils are a bit to light i fine . Stay away from full synthetic oils ( 50/50 ok) as the oils are to slippery and dont want to bond rather run off the matting surfaces GEN #3 chevy guys lernt this ( the hard way ) with pre mature came shaft failure as well as ring failure; Its just not a risk Im willing to take with a DOHC engine. hope that Ive been off some help. =;

Price is good to go by. Just don't touch anything under sixty bucks.

Last service I used Mobile 1 5W-50W silver bottle. It seems like a bit too thin.

Shell helix ultra 5W40 works extremely well so far!

I've noticed that too. Seemed to burn a little. I moved to some thicker motul stuff, but it was $90 for a 4 litre bottle (and you need every drop).

There is an viscosity recommendation in the owner's manual. I think it may have been 15W. I'll check when I get a chance.

I'm using Castrol GTX 10W30 at the moment very happy with it
I'm changing the oil every 5000 kays so I'm not spending mega bucks each time

Supa Cheap had Castrol Edge 5W30 on special last month for $30, usually $45, but missed out, that's a top quality oil

The IS manual recommends a 5W30 or 10W40 oil
You'll find that the 5W type is more expensive

I just found the manual for the Iggy, and there's an interesting paragraph in part 8-7:
Quote:
Be sure that the engine oil you use comes under the quality classification of SE, SF, SG, SH, SJ or SL. Select the appropriate viscousity according to the above chart.

For temperatures above -20°C (-4°F), we strongly recommend you use SAE 5W-30.


However, there's also a little chart which shows that 5W-30 is good up to 30 degrees Celsius, and says to use 10W-40 for up to 40 degrees Celsius (I'm guessing that's what the 30 and 40 mean). Don't know about where you guys are at, but it's 29 degrees here, and it's not even 2 weeks into October... I'm guessing the Japs don't have 40°C days often.

The 30 in 5w-30 is a viscosity rating ('SAE' rating) and the numbers are not that directly linked to temperature. More here (which just happened to be what google found first):

Yeah, there actually isn't much in that exact viscousity. I ended up with the 5W-40 helix. I'll see how that goes.

Norther Exposure may be right about the full synthetic oils. Ive read are few chev forums and they say the same thing.Im not willing to take the plunge either.As are rebuild would not be cheap . [-o<

do those purolator filters have magnets inside them?
there are some US brand filters like this but they cost about $25
I've been trying to find those magnet brackets that fit around the outside of oil filters but haven't had much luck
