What is the point in spending money on something that won't really help?

Because it does help. There's more to oil than just protection or engine longevity (but on that topic, a synthetic will last a lot longer than a mineral); I pay the extra for smoother performance alone. It's like HD vs normal TV: you will still see your show fine in non-HD, but why not enjoy it in a way that looks/feels better?

Birds: do you know much about Royal Purple 10w40? My mechanic is trying hard to flog it to me, as its slightly cheaper than Edge, and I can buy it by the litre. Also got given a copy of the infamous Street Commodores oil review (mechanic claimed that the threat of legal action was the reason for the article's retraction)

Print out the street commodores oil review, and then use it to wipe your ass.

Regular RP is a Group IV oil, XPR is Group V. If you can get RP cheaper than Edge, go for it. People seem to have alot of success with RP on here with their skylines, no negatives that I can remember.

No personal experience with it, but 10w40 is the favourite RB friendly grade and there have been a few on here using Royal Purple's rendition with good reports, so I'd say go for it.

Royal Purple is actually purple oil, i know because my mate puts it in his S15 and we were pouring his 5 left over bottle with about a liter in each into one bottle so it can be taken for a service. I was confused why and how they do it lol, purple additive ?

using it in an LSx, not an RB lol, used to use Motul 8100 Xcess 10w40 in that.

Been reading an absolute shitload of LS forums and BITOG lately, the main evidence for the Edge comes via Steve from Mainlube, who has filtergrams to back up his claims that Edge 10w60 is second only to the Mainlube 10w60 engine oil. (as well as being in that field etc).

Was mostly concerned with whether the regular RP was in fact a Group 4, or whether it was still a 2/3 with a custom additive package (as far as I can read it has a lot of ZDDP and Moly in it).

Moodles2: on further reading, it appears that the Timken machine used for that test is actually meant for testing out greases not engine oils. Also half of the oils mentioned in that review no longer exist.

You won't believe how many morons keep bringing up that street commodores oil review in this thread alone. Everytime pointed out it's a grease testing method.

The mechanic has a stack of copies of the article printed out (by RP by the looks of it) sitting on the counter lolz.

In the end, 10w40 RP HPR is about the same price as paying full retail for Edge 10w60, went with the Edge as Supercheap had their 20% off sale, and BITOG / LS1.com.au had more people who had empirical evidence of the Edge being a good oil rather than "it feels better".

The change from the mineral 25w50 to the Group 4 10w60 is noticeable though; all of the lifter noise on cold startup has gone and it seems to be able to rev more freely. (not anal enough to also get the UOA).

Lets say the oil needs changing , according to manufacturers specs and isn't changed!

What noticeable signs or symptoms for the driver will show................( before the motor seizes and before significant damage.)

(I tend NOT to do the kilometres but tend to change beyond 6 months and more likely 12 months or more.One car is just used occasionally on weekend eg, 120km to coast and back, whilst the other is a daily but still less than 5000km a year)

Noisy lifters; engine runs/feels/idles rough; can make for a smokey exhaust from the oil breaking down. It can actually be a tough thing to notice until things get really bad. I've seen cars with no oil change for 75,000km and the driver hasn't noticed a thing (to be fair, driver was female). This is why I immediately scrap potential cars that say "lady owner" when I'm looking for cars. Lady owner doesn't mean treated kindly, it means not friggen serviced. I'll take the hoon with a bunch of service receipts thank you. Anyway...

The funny thing about oil being left in too long, is the point you get to where it is healthier to leave the unchanged oil in there for the rest of the engine's life. Like above in my 75,000km example, the engine internals had worn to a point where they depended on the sludgy oil to take up the slack...so removing this and replacing it with good oil actually made the engine noisy and more prone to failure lol.

This is why I'm against engine flushing with those engine cleaners...particularly with older engines. They are basically turpentine and kerosene mixes that removes good sludge from the engine. There are parts of the engine that new oil can't easily get to (or stay there) and you're removing the "good stuff" from there = bad!

Oil in a weekender car for a year won't kill it, though I wouldn't leave it much longer than a year before changing it...time kills fluids too.

+1 for not buying off woman drivers, i wouldnt mind a highly serviced but driven hard vehicle. As long as it hasnt seen the rev limiter. but lets be serious all our cars have been redlined in the past but a carnt who redlines it every second week can fark off.

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
