I'm putting Castrol Black Edge 5-w30 Full synthetic in my GSR, just curious on what everyone else uses

 

mobil 1 5w-30

 

corn

 

I ran quaker state 10w30 for 7 years in my GSR and B20. Many track days and driven all over the country. Synthetic is overrated IMO.

 

haha. However olive oil has more anti oxidants than corn oil, but on the other hand, less thermal durability.

I use Castrol Syntec. Though scientifically seems like a better option, I still prefer regular mineral oil; I think i'll swtich back.

 

What ever is on sale at wal-mart in 10w30. Except for the cheapo one in the blue bottle forgot the brand but i get that for my girls car, lol.

 

Valvoline 5W30. I'm still superstitious about synthetic.

 

Mobil1: Great for cold weather starting, doesn't burn a drop.
Oil Changes extended to 12,000km

 

I use synthetic, because I think that it offers better protection for the track. Oil temperature is interesting, measuring 200-210, or whatever number you get may not represent the temperature that the oil sees, say at the cam level, or up around the head. Interesting chart, though somewhat old, most of the number have not changed a lot. Most non-synthetics Flash from 390-410, and synthetics from around 450 and up, depending on weight and brand/formulation. Interestingly, the chart shows little difference in the synthetics, unless your budget allows Amsoil or Redline. Part of the chart problem is that some changed formulation of synthetics since the chart and are now using some or all hydro-cracked. I followed and used Mobil 1 for years and they even advertise differently than they used to. I believe that they have a blend of constructed and cracked oils. Not making a big statement about types as most are still good at the higher temperatures. A very interesting read and charts, lots of information is a short article.

used to run castrol gtx 10w40, but the motor was still burning it durinig track sessions (bad rings); then ran 20w50 for one track weekend

 

Mobil 1 10w30

 

I use M1 5w-30, and their filter.

 

I use Honda Genuine HG synthetic blend 5w-30. I love that stuff

 

Great info. Looks like I'm using the wrong brand. Maybe I'll use synthetic in my next oil change.

 

Penzoil hyper synthetic 5w30 even my Acura dealership switched from mobil 1 to penzoil hyper synthetic! iv used this every since i assembled my ITR motor from the dealer! great oil!

 

Interesting how the articles can sway people and in what direction. I use synthetic, but am less brand conscious. I am told that German/Euro compliant Castrol 0-30 is true synthetic. I use Store Brand Synthetic in family cars and go 6-7.5k and my mechanic just asked what I used. Said the TL head looked almost new at 220k miles. Got the same reaction in an older Integra with 275k miles. Since most of the synthetics are similar in flash and pour, and better than dino, they get to flow temp sooner and less burn off, or heat damage. To me its is still about some savings among the synthetics. I pay the extra for the oil during track season for the Integra that I track.

My answer then is synthetic and store brand or sale price.

 

Mobil 1 10w30 full synthetic.

 

AMSOIL 10w 30 is by far the best oil on the Planet!!!

 

mobil 1 Extended Performance 10w30.

 

B18C..I always use Royal Purple. Currently running 10w30..weather has been in the 100's lately

 

AMSOIL XL 5w-30 best stuff on the planet for my B18C1. Also put it in my
500+ whp 2005 GTO

 

When I owned my Prelude it had a oil burning problem like most H22 and I found Castrol GTX worked the best. Surprised the Ferrari link only recommended Penzoil and Valvoline. I did like Penzoil as well. I tried Synthetic in the Prelude and it just drank it.
The Integra seems to like the Synthetic, no burn off.

 

The Ferrari link gives a good understanding of oil pressure and flow. I put less stock in brands especially if the article is not updated. The other article,

http://micapeak.com/info/oiled.html

though old seems to more break along synthetics vs non. Even "cheap" synthetics have better flash and pour than non.

 

kendal oil will probably have to change brands now since they changed there formula.
