| Help! Best Dino & Syn. oil?

Level 2 - 51 to 100 posts |
I was reading the post by TallPaul and the discussion about Redline. I thought I had a handle on motor oil, but all the talk about tacky oil, Esters, seals, etc.. my brains fell out and rolled under my desk.
My questions is which Dino oil & Syn. oil is good for a daily driver? Please back up your opinion with some shred of fact. Driving details: U.S. driver, 1995 F-150, 300 miles a week, 140k miles on my baby. I know I am opening a can of worms with this discussion, since oil preferences are like talking about religon or politics but, inquiring minds want to know. |

I've been a member at bobistheoilguy for over 3 years. I've learned a few things but mainly that any oil will do.
If your changing the oil every 3-4k miles, stick with any good dino/synblend such as Motorcraft, Havoline, Chevron etc. They are all good. When it comes to Synthetics, M1, Amsoil, Redline and the German Castrol are all excellent choices. I like M1 and Amsoil for daily drivers and would prefer RL for racing due to it's uniquie polyolester chemistry. You can't go wrong with any oil today IMO. Don't sweat the stuff always being talked about on here and on Bob's. It's for the fanatics (I'm one of them  ). |

I could not have said it better than Buster did (though I would have thrown Valvoline in the list--personal bias
 ).
My Baby: 1995 F150 supercab, short bed, 2wd, 4.9 L, 5 speed stick, 120,000 miles, about 200 miles per week. |

http://www.mr2.com/ARTICLE/Mobil1.html I do not think that wear is an issue with current oils and well maintained engines. However, given a chance minerals will sludge and will certainly leave deposits. Synthetics are less likely to cause these problems. Synthetics are performance oils for either extremes, performance engines or long OCIs. If you do not need these benefits then they ar not the oil for you as they are expensive or are they. If you have your car serviced or take into account your time in changing oil, perhaps you can have a performance oil for free, and not many perforance parts are free. The main benefit of esters are in high temp situations like racing and ability to reduce viscosity. |

IMHO, best value are the dino Delvac Super and Delo, for extreme conditions, Delvac-I and Mobil-I.

IMO
Amsoil is the best synthetic Have 28 yrs of experience using it (since 1977), they have been on the market the longest with Mobil a few years less. All the other brands are in the last 5-10 yrs. Havoline is the best dino. My fleet trucks (leased by gov't) used this for more than 10 yrs. My last truck, a 1999 K2500 Chevy Suburban got 5000 miles OCI, usually used about 1/2 qt of less in 5000 hard miles of use by a survey crew. Truck was turned in in 2003 and was in very good condition at 125,000+ miles. |

My understanding of Amsoil is that they are so close to Mobil 1, that their is little value in using it. At one time, I've heard several knowledgable people say Amsoil was the best. But now, although still very good and very top notch, they are on par with Mobil 1. Amsoil seems to have severe oxidation issues. They too formulate to a price point.

An oil analysis (5W-30, Amsoil XL) I sent in, used for 13,000 kms in seven months came back at 8w-30 and still good for use until next service appointment which was 5,000 kms and 3 months later. The maximum oil change interval for this product is 12,000 kms or 7,500 miles or six months whichever comes first.

Could you post the viscosity given in the analysis report? There is no 8w category. There is only 0w, 5w, 10w, 15w, 20w, and 25w. |

The analysis report stated 8W. This characteristic when new was 5W. Perhaps its a concept that is not grasped at first glance but worth a second look.

Well I am working off of THIS CHART but maybe the lab has a different classification. What lab did you use?

O.A.I Testing in Cleveland OH. I know what your saying about the SAE classification not fitting but don't forget this is an analysis and its result will show any number that the test produces. I was also not born yesterday to realize an SAE 8w doesn't exist on the store shelves but if that's what the reports says & I can read, and it's put out by guys wearing whites...
It could be that the TAN & TBN numbers to name a few has something to do with how the results are arrived at. Thanks for the great chart by the way. |

The Amsoil XL line, when it was GF-3, was a good product, although expensive compared to the Mobil 1 PAO GF-4 line. The new reformulated GF-4 specs for the XL line aren't that impressive. I'd get a PC discount and use their ASL/ATM 30wt stuff over the XL line.

My choice for best synthetic is Redline; for dino (conventional) is Maxlife--well I guess that is cheating because Maxlife has about 15% PAO in it, but essentially is a dino. But I suppose the really best dino is a Group III, normally called "Full Synthetic." In that respect, Synthetic Maxlife may be the best choice.

What catagories are you rating this brand so high? When you check out some comparison charts, you'll see some surprises.

I assume you are refering to the Maxlife Synthetic. Here are some impressive numbers for Maxlife Synthetic 10w30 from the Valvoline web site as of Sept '04: Viscosity at 100C: 11.5 cSt TBN: 10 Flash Point: 230 C Pour Point: -42 C NOACK % at 250C: 8.3 Zinc: 1000 ppm Phosphours: 920 ppm Calcium: 3870 ppm Moly: 290 ppm Also lists "Approvals/Performance Levels": ACEA A3-02 BMW Longlife 98 Volkswagen 502.00, 505.00 and a few others like SL/CF Nice stuff! |

Very nice specs on the Amsoil. That would be PAO, right? Can you show me a Group III that compares well to the Maxlife Synthetic (which according to the MSDS appears to be a Group III)?
