Hi
I just bought a samurai model 93 in a very good condition and I am pretty happy with it ,but I have a problem
I gave it to a gas station to change oil and they added a full synthetic 15-50 bp visco 7000.
The Service manual says that the appropriate oil viscosity is 0-30 .
After the oil change I found that the engine runs "a bit" warmer .
Do you thing that I have to change the oil again with the appropriate one?
Regards

I sure wouldn't worry about it for the warm weather.
I run 20/50 Summer, 10/30 Winter
Test and performance engines I never run less that a 15/40

The only thing we have noticed is the Synthetic oils
seem to leak more when conventional ones don't

I would definitely agree with Wild, don't know the science but have sure seen the effect.

I would drain out three quarts and save it and put regular 10-w30 in it untill full again and give it a try, make sure you use a good filter like wix/napa gold or nascar filter they sell.

Hold on, I thought you weren't supposed to mix synthetic and conventional oils?? Is that just a "wives tale"? I say... :oGET THAT DAMN 50 WEIGHT OUTTA THERE NOW! :o It may not immediately cause the demise of your motor, but will contribute, especially if you drive hard.

   You are right that you shouldn't mix petroleum and synthetic...never tried it but they say thats the rule......
   202,000km on my wifes 92 Kick 16v says your incorrect on the 50w, we drive hard and I use the extra protection for the summer and switch to 10/30w for our darn cold winters.
But thats just my opinion and opinions are like belly buttons...everybodies got one.

Well here we have the option of buying a Synthetic Blend
which is both blended in the bottle, but then again, the
oil Co. is doing this so they have the additive package
worked out.

You should go as thin of an oil weight as possible without a rod knock,and the oil temp I like to run is about 212 deg. the faster the oil goes through the bearings the more heat it pulls out, if the oil sits there it burns up the oil first then the bearing period. I ran 10w in my vw race engine with a 96 pass oil cooler on a 10" hayden fan so I could control the temp, most people don't even know what there oil is doing or care.

I tend to agree......
but I have also found that the severe service we do with oour vehicles, those with small engines, that the heavier oils serve them well.......my 240Z drag car we did the same lightweight oil trick, but high revvers on the street i have stuck with tried and true Castrol GTX
20/50summer-10/30 winter

The "clearances" in the engine are important too ... an old tired engine will have larger clearances and IMO benefits from a thicker viscosity. I like 10w-50w syn in my old engine, but when it gets a rebuild, I'm going thinner ...
