I've got a 97 gsr w/ 75k on it. I run it pretty hard. The weather here is hot now. (65-100) What's the best oil to use? I've heard that once you run synthetic you can't go back so I was thinking of using a blend.

 

MOBILE 1

 

use mobil 1 for both my Type R and GSR

 

there's been some great discussions on this in the past (search).

that being said, I like Castrol GTX 5w30 on the dino side, and Mobil 1 5w40 (or 10) on the Syn side for cheaper, readily available oils.

you can switch back and forth, but try for consistency...it takes a few chances to fully flush out old oil.

 

run 10w-30 hotter months and 5w-30 in colder months

I run Mobil 1 10w-30

I would like to run Redline Oil but its way too expensive and isn't readily avaliable

 

honda 10w-30.

 

How about for turbo applications....any different?

heard that 5w is not thick enough for the turbo...

 

i always thougth the second number was how thick the oil was....

 

really? i thought the first one was...learn something new everyday

haha i got confused with viscocity..

i always use castrol 10w30. them syn stuff is too rich for my blood. i wished i could afford mobil 1

im pretty sure the first number is thickness...but yeah summer/spring 10w30, and fall/winter 5w30
i use mobile 1 syn.

 

I think it's like this:

1st number is viscosity properties when the oil is cold (it acts like a 10 weight oil)
2nd number is viscosity properties when the oil is hot (it acts like a 30 weight oil)

Basically a 10w-30 allows the oil to remain fairly thin when the temps are cold, and still remain stable when the temp rises.

 

Redline is the best.

 

I use castrol GTX 10w30 year round.

140k miles on the odo.

I would only use 5w30 if I lived in below freezing temps. we get maybe one of those a year in houston. so it isn't worth it.

exactly

 

honda oil LOL .. i use 5w30 full sythetic castrol.. its done me good for a good period of time now... no trouble so ill stick with it...where is the link for the oil compareson? i looked for it didnt find it...

 

I use castrol 10w40, so far so good! my car has 160K on it and runs like new.

 

Neo full synthetic

 

I use 10w-30 Vavoline Maxlife, for my 94gsr with 120k miles.

I used to use 10w30 Castrol GTX or Pennzoil.


But "the best" oil at a "affordable" range has to be Mobil 1. I heard Amsoil was really good but no thanks for me at $8+ a qt.

 

I use MOBILE 1

 

i use honda oil when i take the car to the dealership for a change, if i do it myself...its mobil oil. mobil produces the base oil for honda and then honda adds its own additive.

 

i use mobil 1 supersyn

i have no complaints

 

Is it the higher the number the thicker the oil?

 

the bigger the number the thicker the oil!

 

Halvoline (Chevron) 5w30
