5 winter 40 is what i use for daily(8100 x-cess Motul) and 5w30 for track (300v Motul)


It all comes down to your change intervals.. You can pretty much run anything if you change it often enough. To know when its often enough i suggest running oil analysis from Blackstone. You will learn a lot about your specific enigne by running those reports...

Lspi..bahhh.. We never had LSPI issues on this car.. We had shit internals from Hyundai. If im not mistaken Lspi was a marketing pitch for a leading brand of oil...

Tell that to the people who ejected pistons and rods out of their block. That doesn't happen from simple spark knock nor basic pre-ignition directly, but either can trigger LSPI events. Catastrophic failure (block windowing) happens due to super/mega knocking which is caused by LSPI events. Do some research. Several auto manufacturers, oil/fuel companies, universities and research organizations have published many, many LSPI articles on SAE. It doesn't matter how strong your pistons and rods are. If it happens, the weakest components will break first.

The main reason why incidents dropped in '14-'16s is because Hyundai changed their tune to reduce boost pressure and offset it with timing. This is why everyone with newer VTs complained about lower boost PSI. Higher PSI and boost spikes cause high enough BMEP values to induce LSPI events. Couple that with calcium content, fuel content, non-synthetic oil, high intake temperature, low coolant temperature (from not being at operating temperature) and carbon deposits in combustion chambers and you have a nice LSPI breeding ground.

I'd also like to think that incidents reduced in part (at least the ones reported here) because smart people read my anti-LSPI tips and followed the protocol as much as feasible for them.

Welcome back X. I read the same article you did the last 3 years.. Im well aware of what they are saying. However im not going sweep what issues Hyundai had with this car Under the LSPI rug. Nor am I going to start talking about which oils will reduce LSPI like the OIl articles do. Ive seen motors blow with all brands including Cerma which was suppose to prevent LSPI according to a few here.

Which specific article are you referring to? I've read more than just one.

We've only known about LSPI for just over two years ago, not three.

No oil can single-handedly "prevent" LSPI but certain chemistry can help to reduce the likelihood.

I for one never claimed CERMA can wholly prevent LSPI, since there are many factors involved, most of which I described in my last post.

I cant recall which specific article, ive read many and watched a few videos that came about, and read many many threads on Bobtheoilguy, also worked some stuff with Motul.. LSPI has been talked about for a few years but your right about 2 years ago i guess is when this forum started to talk about it.. When Cerma John came about is when the topic really took off here.. I didnt say you stated Cerma would single handedly prevent LSPI, but there were a few here who did..
